Answer:

Width - 12ft  Length - 30ft

Step-by-step explanation:

Width is 12ft

Length is 30ft

Depth is 6ft

The length, 30ft, is 2.5 times longer than the width which is 12 ft which confirms the two dimensions to be correct.

When you multiply all three of the dimensions of the swimming pool you will get 2940 cubic feet

You have used the Distributive Property to transform numerical expressions such as (5)(3) + (2)(3) to (5 + 2)(3). How would you
3241004551 [841]

Step-by-step explanation:

5x + 2x

that is the same as (5 + 2)x

and that is the same as (7)x = 7x

so, for the second part of the problem we are actually comparing

7x

and

7x - 1

there is therefore no way for the two expressions to deliver the same value for the same x.

the values of 7x are always larger by one than the values of 7x - 1

so, e.g.

x = 1

5×1 + 2×1 = 5 + 2 = 7

7×1 - 1 = 7 - 1 = 6

x = 2

5×2 + 2×2 = 10 + 4 = 14

7×2 - 1 = 14 - 1 = 13

x = 3

5×3 + 2×3 = 15 + 6 = 21

7×3 - 1 = 21 - 1 = 20

x = 4

5×4 + 2×4 = 20 + 8 = 28

7×4 - 1 = 28 - 1 = 27

x = 5

5×5 + 2×5 = 25 + 10 = 35

7×5 - 1 = 35 - 1 = 34

What are the x and y-intercepts of the graph of -3x+4y=-36?
Nuetrik [128]
The x intercept is where the graph intercepts the x axis or where y=0
the y intercept is where the graph intercepts the y axis or where x=0


xintercpet
replace y with 0 and solve for x
-3x+4(0)=-36
-3x=-36
divide -3 both sides
x=12
xintercept=12

yintercept
replace x with 0 and solve for y
-3(0)+4y=-36
4y=-36
divide both sides by 4
y=-9


xint=12
yint=-9

What is the factored form of the expression?<br><br> d^2 = 36d + 324
Aleonysh [2.5K]

Answer:

(x-43.45)(x+7.45)=0.

Step-by-step explanation:

We have the quadratic equation d^{2}=36d+324 i.e. d^{2}-36d-324=0

Now, the roots of the quadratic equation ax^{2}+bx+c=0 are given by x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}

So, from the given equation, we have,

a = 1, b =-36 , c = -324.

Substituting the values in x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}, we get,

x=\frac{36\pm \sqrt{(-36)^{2}-4\times 1\times (-324)}}{2\times 1}

i.e. x=\frac{36\pm \sqrt{1296+1296}}{2}

i.e. x=\frac{36\pm \sqrt{2592}}{2}

i.e. x=\frac{36\pm 50.9}{2}

i.e. x=\frac{36+50.9}{2}  and i.e. x=\frac{36-50.9}{2}

i.e. x=\frac{86.9}{2}  and i.e. x=\frac{-14.9}{2}

i.e. x = 43.45 and x = -7.45

Hence, the factored form of the given expression will be (x-43.45)(x+7.45)=0.
