The volume is the product of three dimensions
V = lwhGiven:
w = x + 1, l = x + 2 and V(x) = x³ + x² - 4x - 4
1) Let's find the height:
x³ + x² - 4x - 4 =x²(x + 1) - 4(x + 1) = (x² -4)(x + 1) = (x + 2)(x - 2)(x + 1)We got h = x - 22) x = 4 m
Volume is:
V = 4³ + 4² - 4*4 - 4 = 60 m³3) x = 4 m
Dimensions are:
w = x + 1 = 5 m, l = x + 2 = 6 m, h = x - 2 = 2 mFull surface area is:
2(lw + lh + wh) =2(5*6 + 6*2 + 5*2) = 104 m²pls help..thanks,,,,
Answer/Step-by-step explanation:
Given, y = k√x
Let's find the following:
a. To find k, using the first pair given, (64, 16), plug in the values of the ordered pair into y = k√x
Thus:
16 = k√64
16 = k*8
Divide both sides by 8
16/8 = k
k = 2
b. To find F, substitute k = 2, and x = 100 into y = k√x
Thus:
y = 2√100
y = 2*10
y = 20
F = 20
c. To find x, substitute k = 2, and y = 10√2 into y = k√x.
Thus:
10√2 = 2√x
Divide both sides by 2
(10√2)/2 = √x
5√2 = √x
Square both sides
x = (5√2)²
x = 25*2
x = 50
d = 50

YLaw of Cosines: c2 = a+ b2 - 2ab cos C
9514 1404 393
Answer:
29.4°
Step-by-step explanation:
The equation can be rearranged to give C directly.
C = arccos((a^2 +b^2 -c^2)/(2ab))
C = arccos((90^2 +55^2 -50^2)/(2·90·55))
C = arccos(8625/9900) ≈ 29.4002°
C ≈ 29.4°

Answer: combining like terms
Step-by-step explanation:
Solve the equation below for x.
cx- 4 = 7
A. x=11/c
B. x=c/3
C. x=3/c
D. x= c/11
Answer:
a. x = 11/c
Step-by-step explanation:
cx - 4 = 7 [add 4 to both sides of the equation]
cx = 11 [divide by c to isolate x]
x = 11/c
Four copies of the triangle shown are joined together, without gaps or overlaps, to make a parallelogram. measurements= 5cm, 13cm, 12cm What is the largest possible perimeter of the parallelogram?
Answer:
Highest Possible Perimeter = 52cm
Step-by-step explanation:
The triangle is not shown. But, the question can still be solved.
The given sides (5cm,12cm and 13cm) of the triangle shows that the triangle is a right angled triangle as proven below:.
[tex]13\² = 5\² + 12\²[/tex]
[tex]169 = 25 + 144[/tex]
[tex]169 = 169[/tex]
Having shown that;
The next step is to determine the highest possible value of the perimeter.
To get the highest possible perimeter;
The 4 triangles have to be joined at the 12cm and 5cm part of each triangle (see attachment).
From the attachment, the perimeter is then calculated as:
Perimeter = 13cm + 13cm + 13cm+ 13cm
Perimeter = 52 cm

What is the value of x?
-4n + 1/3m + 4n - 4/5m
Answer:
[tex]-4n+\frac{1}{3m}+4n-\frac{4}{5m}=-\frac{7}{15m}[/tex]
Step-by-step explanation:
Given the expression
[tex]-4n\:+\:\frac{1}{3m}\:+\:4n\:-\frac{4}{5m}[/tex]
Group like terms
[tex]-4n\:+\:\frac{1}{3m}\:+\:4n\:-\frac{4}{5m}=-4n+4n+\frac{1}{3m}-\frac{4}{5m}[/tex]
Adding similar elements: -4n + 4n = 0
[tex]=\frac{1}{3m}-\frac{4}{5m}[/tex]
L.C.M of 3m and 5n will be: 15m
so adjusting fractions based on the LCM
[tex]=\frac{5}{15m}-\frac{12}{15m}[/tex]
Since, the denominators are equal, combine the fractions: [tex]\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}[/tex]
[tex]=\frac{5-12}{15m}[/tex]
[tex]=\frac{-7}{15m}[/tex]
[tex]=-\frac{7}{15m}[/tex]
Therefore, we conclude that:
[tex]-4n+\frac{1}{3m}+4n-\frac{4}{5m}=-\frac{7}{15m}[/tex]
25% of 96 is what number round to the nearest tenth of necessary
Answer:
y = .25 x 96
y = 24
This is the answer.
Step-by-step explanation:
25% is the same as 0.25
25% = 25/100 = 0.25
Multiply 0.25 with 96
0.25 x 96 = 24
24 is your answer

evaluate the expression when c=2. 6c/2
Answer:
6Step-by-step explanation:
Given the expression g(c) = 6c/2, we are to find the value when c = 2
Substitute c = 2 into the expression
g(2) = 6(2)/2
g(2) = 12/2
g(2) = 6
Hence the result when c = 2 is 6
If I buy 5 plants from the garden centre at £3.00 a plant how much do the plants cost? If I have a £20 note how much change will I get?
Answer:
They will cost you £5.00 total
Step-by-step explanation:
If the plants each cost £3.00
You multiply the amount of plants, in this case is 5 by the price :-
5×3.00
= £15.00
You then subtract the total from the cash
15.00 - 20.00
= £5.00

(1, 1) and (4, 3) slope
Answer:
[tex] \huge \boxed{ \boxed{ \frac{2}{3} }}[/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
From the question we have
[tex]m = \frac{3 - 1}{4 - 1} = \frac{2}{3} \\ [/tex]
We have the final answer as
[tex] \frac{2}{3} \\ [/tex]

Answer:
a) 15 + 25x ≤ 70
b) 60 + 15x ≤ 500
Step-by-step explanation:
a) Let x represent the number of calculators that Ms. Burgos can buy. since each calculator cost $25, then the total cost of calculator = $25 * x = $25x
She bought three notebooks costing $5 each. Money spent on notebooks = 3 * $5 = $15
Hence the total money spent = $15 + $25x = 15 + 25x
She has only $70, therefore:
15 + 25x ≤ 70
b) Cayla initially has $60.
Cayla is saving $15 per week. Let us assume she saves for x weeks, hence money saved by Cayla = 15x
Therefore the total money saved = 60 + 15x
Since Cayla needs to save atleast $500, hence:
60 + 15x ≤ 500
