Elenna [48]

Answer:

${(x - 6)}^{2}$

Step-by-step explanation:

$= {x}^{2} - 12x + 36 \\ = {x}^{2} - (6 + 6)x + 36 \\ = {x }^{2} - 6x - 6x + 36 \\ = x(x - 6) - 6(x - 6) \\ =(x - 6)(x - 6) \\ = {(x - 6)}^{2}$

borishaifa [10]

To calculate it use pythagoras: a^2+b^2=c^2
7^2+10^2=49+100=149

calculate the square root: $\sqrt{149}=12.2$
so the diagonal is about 12.2 inches long

A beachball has a surface area of about 615.75 square meters. Find the

Genrish500 [490]

Answer: The radius of the ball is 7 meters.

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Surface area of a sphere: 4 π r^2

Replacing with the value given:

615.75 = 4 π r^2

Solving for r (radius):

615.75 /4π= r^2

√(615.75 /4π) =r

r = 6.99 = 7m (rounded)

The radius of the ball is 7 meters.

Solve the proportion 40/z+1 = 15/6

vovangra [49]

Answer:

Step-by-step explanation:

$\frac{40}{z + 1} = \frac{15}{6} \\$

<u>Cross multiply </u>

That's

$15(z + 1) = 40(6) \\ 15z + 15 = 240$

<u>Send 15 to the right side of the equation</u>

$15z = 240 - 15 \\ 15z = 225$

Divide both sides by 15

$\frac{15z}{15} = \frac{225}{15} \\$

We have the final answer as

Hope this helps you
