Answer:Yes

Step-by-step explanation:

For 6(6+x), you have to multiply what’s in the parentheses with 6. Multiply 6 and 6 first which gives you 36. Then multiply 6 and x which gives you 6x. Therefore, it’s simplified as 6x+36

The area of the cross section of a sphere at the largest point is 100π square miles. what is the total surface area of this sphe

Firlakuza [10]

The cross-section of a sphere is a circle . The area of a circle can be calculated by the formula A= $\pi\r^{2}$ Where r is the radius of the circle.

Given : $\pir^{2} = 100\pi$

Solving for r we have:

$r^{2} = \frac{100\pi }{\pi}= 100$

Or r= 10.

The area of a sphere is calculated by the formula :

$SA = 4\pi R^{2}$

Substituting r value we have:

SA= $4\pi\ 10 ^{2} = 400\pi$

The total surface area of this sphere is 400π .

If x=-7 is a root of the equation x^2+kx+49=0, then k=

aleksley [76]

Answer:

$k=14$

Step-by-step explanation:

Given:

$x^{2}+kx+49 = 0$

$x = -7$

Substitution can be used to find the value of $k$ :

$(-7)^{2}+(-7)k+49 = 0$

$49-7k+49 = 0$

$98 -7k = 0$

$k = 14$

Hope this helps :)
