Suppose you know the perimeter of a rectangle. How can you write
an equation for the area in terms of the length of a side?
Step-by-step explanation:
L+W+L+W=26 so 2L=26–2W and you can find length from the perimeter as L=13−W
LW=42 so L=42/W is the other way to find the length, from the area. Both ways require you to know W, but if you have both pieces of information the two answers for length must be the same 42/W=13−W, and you solve this:
42=13W−W2
W2–13W+42=0
(W−6)(W−7)=0
Either W−6=0 or W−7=0

Plzzz hurry
Answer:
8
Step-by-step explanation:
If each baseball= 4 homeruns, and Chester has 5 baseballs next to his name (20 homeruns), then Evan hit 12 home runs because 4*3= 12 and he has 3 baseballs next to his name.

10) What changes when a figure is
transformed by a reflection, rotation,
or a translation?
A) its area
C) its position
B) its size
D) its perimeter
Answer:
size because when a figure is squeezed, it shrinks and changes the size
Answer:
Its Position
Step-by-step explanation:
Reflection-when the shape is reflected over an axis
Rotation-when the shape is rotated around a singular point
Translation-when the shape is moved up/down or left/right
None of these change any part of the shape it just moves the shape around. :)

If a is inversely proportional to x, a=15 when x=25 find the constant of variation, k
Answer:
Step-by-step explanation:
"Inversely proportional to x" in this situation is represented by a = k/x.
Find k:
Let a = 15 and x = 25, then calculate k:
15 = k/25)
Multiplying both sides by 25 yields k = 15(25), or k = 3/5

Rachel's car has a 12 gallon gas tank and
she uses about 0.5 gallons per day driving to
school. Write an equation describing the
number of gallons of gas, g, Rachel has in
her car and the number of days, d, she has
driven to school.
please help meeee
Answer:
g=dx
Or, if you'r wanting the solved equation..
12 = 0.5 x 24
Step-by-step explanation:
If she has 12 gallons in her tank and you look at what it's asking us to do, "..number of gallons of gas, g" pairs up with the 12 gallons while the 0.5 gallons used per day pairs with "...the number of days, d, she has driven to school."

What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the function H =f(t) gives the temperature, HF, of an object t minutes after it is taken out of the refrigerator and left to sit in a room.
(a) The value of the function after 2 minutes will be,
[tex]H=T^t\\H=(T)^{t+2}[/tex]
(b) The value of the function at 15 F will be,
[tex]H=(15)^{t}[/tex]
Therefore, the value of the function after 2 minutes later will be [tex]H=(T)^{t+2}[/tex]. The value of the function at 15 F will be [tex]H=(15)^t[/tex].

Substitute t = 3 and t = 6 to determine if the two expressions are equivalent.
3 (2 t + 5) 6 t + 15
Which statements are true? Select the three correct answers.
A. The value of both expressions when t = 3 is 33.
B. The value of both expressions when t = 3 is 23.
C. The value of both expressions when t = 6 is 41.
D. The value of both expressions when t = 6 is 51.
E. The two expressions are equivalent.
F. The two expressions are not equivalent.
Answer:
A.The value of both expressions when t=3 is 33.
D.The value of both expressions when t=6 is 51.
E.The two expressions are equivalent.
Step-by-step explanation:
We are given two expressions.
3(2t + 5)
6t + 15
Now let's find the value of these two expressions when t =3 and t = 6
When t =3, the value of the expressions:
3(2*3 + 5) = 3(6 + 5) = 3(11) = 33
6*3 + 15 = 18 + 15 = 33
So the value of both the expressions is 33 when t = 33.
When t = 6, the value of the expressions:
3(2*6 + 5) = 3(12 + 5) = 3(17) = 51
6*6 + 15 = 36 + 15 = 51
The value of both the expressions is 51 when t = 51.
So the following statements are true:
A.The value of both expressions when t=3 is 33.
D.The value of both expressions when t=6 is 51.
E.The two expressions are equivalent.

For the right triangles below, find the values of the side lengths d and a.
Round your answers to the nearest tenth.
Answer:
a = 1.4 and d = 6.9
Step-by-step explanation:
To get the value of d and a, we will use the SOH CAH TOA identity
For the first tringle;
Opposite = d ((opposite angle 60 degrees)
Adjacent = 4
Tan theta = opp/adj
Tan 60 = d/4
d = 4tan60
d = 4(1.732)
d = 6.9
For the second triangle;
Opposite = a
Hypotenuse = 2
Since sin theta = opp/hyp
Sin45 = a/2
a = 2sin45
a = 2(0.7071)
a = 1.4
Hence a = 1.4 and d = 6.9

Which ordered pair is the solution of the following
system of equations?
3x + 2y = 4
–2x + 2y = 24
A. (2, -1)
B. (2,-5)
C. (-4,8)
D. (-4,-8)
Answer:
C
Step-by-step explanation:
Given the 2 equations
3x + 2y = 4 → (1)
- 2x + 2y = 24 → (2)
Multiplying (2) by - 1 and adding to (1) will eliminate the y- term
2x - 2y = - 24 → (3)
Add (1) and (3) term by term to eliminate y
5x + 0 = - 20
5x = - 20 ( divide both sides by 5 )
x = - 4
Substitute x = - 4 into either of the 2 equations and solve for y
Substituting into (1)
3(- 4) + 2y = 4
- 12 + 2y = 4 ( add 12 to both sides )
2y = 16 ( divide both sides by 2 )
y = 8
solution is (- 4, 8 ) → C

What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. When the proportion is multiplied by 100%, a percentage is found.
The proportion of people who own a bird is:
p = 0.04 + 0.02 = 0.06.
Hence the percentage is of 6%, which means that option C is correct.

When I have walked 20% of the way to school, I have 1200 metres more to walk than when I have 20% of the walk remaining.
How far, in metres, is it from my home to my school?
Answer:
The house is 2000 meters from the school.
Step-by-step explanation:
Given that, when I have walked 20% of the way to school, I have 1200 meters more to walk than when I have 20% of the walk remaining, to determine how far, in meters, is it from my home to my school the following calculation has to be done:
100 - 20 = 80
80 = 20 + 1200
80 - 20 = 1200
60 = 1200
1200/60 = 20
20 x 100 = 2000
Therefore, the house is 2000 meters from the school.
