Hi , the answer is 8 .

The diameter is twice the radius.

4 times 2=8
4+4=8

Hope this helps and have a nice day .

Y=-6-x is not equal to 2x+y=12. Both sides were not divided by two when it was simplified.

The LCM of the two numbers is 60. The difference of the two numbers is three

Drupady [299]

List the factors of 60. Then look at the factors that are 3 apart, a difference of 3. This gives you 12 & 15. 12: 12, 24, 36, 48, 60 15: 15, 30, 46, 60

Answer:

Step-by-step explanation:

base = 784 sq in² 28 in tall pyramid

each side of the square base = √784 also equals 28

using the Pythagorean theorem the length of each side of the pyramid from the base to the point is

(side/2)² + height² =( length of the pyramid face)²

(28/2)² + 28² = 196 + 784 = 980 = (face length)²

face length = √980 = 31.3

area of the pyramid = 4 sides × area of each face + the area of the base

= 4×[(1/2)(base)(face length)] + side²

= 4(1/2)(28)(31.3) + 784

= 2537 sq in² Not in the solution set

A section of a rectangle is shaded. The area of the shaded section is 63 square units. What is the value of x?

ella [17]

Answer:

$x=11$

Step-by-step explanation:

We have been given a graph of a rectangle. The area of the shaded section is 63 square units. We are asked to find the value of x.

We can see from our given graph that shaded section forms a trapezoid, so we will use area of trapezoid formula to find the value of x.

$\text{Area of trapezoid}=\frac{(a+b)}{2}\times h$ , where, a and b represents the parallel sides of trapezoid and h represents height of trapezoid.

Upon substituting our given values in above formula we will get,

$63=\frac{7+x}{2}\times 7$

$63=(7+x)*3.5$

Upon dividing both sides of our equation by 3.5 we will get,

$\frac{63}{3.5}=\frac{(7+x)*3.5}{3.5}$

$18=7+x$

Let us subtract 7 from both sides of our equation.

$18-7=7-7+x$

$11=x$

Therefore, the value of x is 11 units.
