Answer:
7m-7m=8n+8n
m=16n
Step-by-step explanation: U must first link the like terms so in order to do so u must bring over the 7m, now before u brought over the 7m it was a positive 7m now that your bring it over it turns negeitive and the same goes for the term 8n when u carry that term over it turns positive now dont let the subtraction sign foul u it still negative as long as its beside the term it is going to be negative guys dont forget that, now on to the next step after u cross over and change signs u start to work out now that the like terms are equal u dont need to worry about them because its given u the go ahead to workout so your main focus is on the subtracting the 7's which is 0 and leaves u with m u dont have to put them but i dont recommend it the u start on the next side u and the 8's which is 16 and u put bk the n u have to put bk the terms its important and thats how u get m=16n.

12 is the complete length and 10 is the number of sides
12x10= 120
Answer:
3. P = 48 units A = 116 units²
Step-by-step explanation:
A = 12 x 12
= 144
Now we can subtract the missing areas. 4 x 4 = 16 and 6 x 2 = 12.
144 - 16 - 12
= 116 units²
P = 12 + 12 + 12 + 12
= 48 units
If ∆MNL ~ RSL, find the value of x

x = 5
Step-by-step explanation:
NL/ML = SL/RL
(3x - 1)/28 = (x + 7)/24
24(3x - 1) = 28(x + 7)
72x - 24 = 28x + 196
72x - 28x = 196 + 24
44x = 220
x = 220/44
x = 5

The water of a tank is initially 24 feet, and it is being
drained at a rate of 3 feet per day. The equation below
expresses the water level, y, in feet, in terms of the number
of days, x, since the tank began draining.
y = 24 - 3x
A scientist might be interested in the x-intercept of this
equation because it represents the moment when the tank
will be empty. Which of the following is the x-intercept of
the equation above?

Classify the polynomial.
4y – 5xz
Answer:
4y-5xz has a degree of 2
Step-by-step explanation:
The degree of an expression the the largest degree of any of its terms.
The degree of a term is the sum of the exponents of the variables in that term.
4
y
=
4
y
1
has a degree of 1
5xz=5x1z1
has a degree of ( 1+1)=2
(5xz)
has a higher degree than
(4y)
Therefore the degree of the expression is the degree of
(5xz) , namely 2

Answer:
x = -8
Step-by-step explanation:
9/4 = (x-10)/x
Cross multiplying,
9x = 4(x - 10)
9x = 4x - 40
9x - 4x = -40
5x = -40
x = -40/5
x = -8
Expression equivalent to a^2-144b^2
Answer:
(a - 12b)(a + 12b).
Step-by-step explanation:
a^2 - 144b^2
This is the difference of 2 squares identity:
a^2 - b^2 = (a - b)(a + b)
So for the given expression we have:
(a - 12b)(a + 12b).
- (as a is square root of a^2 and 12b is the square root of 144b^2.).
Given line 1, with coordinates (-7,-3) and (4,7), and line
2 with coordinates (7,-7) and (-3, 4), find the slope of line 2
Answer:
-11/10 (fraction) or -1.1 (decimal)
Step-by-step explanation:
The slope formula is m=(y2-y1)/(x2-x1)
x1 = 7
x2 = -3
y1 = -7
y2 = 4
So, it’s: (4 - (-7))/(-3-7)
= (4+7)/(-3-7)
= (11)/(-10)
= -11/10 or -1.1

Answer:
Prism A: 264; Prism B: 265.125
Step-by-step explanation:
✔️Surface area of the triangular prism = base area + Perimeter*Height of prism
Base area = ½*bh
b = 6 cm
h = 8 cm
Base area = ½*6*8 = 24 cm²
Perimeter of base = 6 + 8 + 10 = 24 cm
Height of prism = 10 cm
Surface area of the triangular prism = 24 + 24*10 = 264 cm²
✔️Surface area of rectangular prism = 2(LW + LH + HW)
L = 5.25 cm
W = 5.25 cm
H = 10 cm
Surface area of rectangular prism = 2(5.25*5.25 + 5.25*10 + 10*5.25)
= 265.125

The length of a rectangle is two times
its width. If the perimeter of the
rectangle is 150 in, what is the length of
the rectangle?
Answer:
length=50
width=25
step-by-step explanation:
=length=2x
=width=x
=perimeter 2(l+b)
=2(2x+x)×150
=2x+x=150÷2
=2x+x=75
=3x=75
=x=75÷3
=25
=length=25×2=50
=width=25

15x-8-3x=16 pls help
Answer:
x=2
Step-by-step explanation:
Combine like terms, add 8 to both sides of the equation, simplify, divide both sides by the same term, simplify
Answer:
x = 2
Step-by-step explanation:
1. Combine like terms
15x - 8 - 3x = 16
1 2 − 8 = 1 6
2. Add 8 to both sides of the equation
1 2 − 8 = 1 6
+8 +8
3. Simplify
12x = 24
12x/12 = 24/12
x = 2
