Answer:
Option B
Step-by-step explanation:
Given: x² + 10x + 13
To make a complete square, we will use (b/2)² to add terms to complete the square where b is the coefficient of x
b = 10 , (b/2)² = 5² = 25
So, add 25 and subtract 25
x² + 10x + 13
= x² + 10x + 13 + 25 - 25
= (x² + 10x + 25) + 13 -25
= (x+5)² - 12
By comparing the options with the previous steps
So, the answer is <u>option B</u>
4×+7y=-12 __ -4x-y=-12 ________ 0x+6y=-24 , so you eleminated by it self 6y/6=-24/6 , you get : y=-4 and then you plug in 4x+7(-4)=-12 , that's your answer 4x-28 =-12 , you divided in both side 4x=-12+28 , 4x=16 , and then x=16/4 =4 , so x=4

Answer:
The area of the roof: ≈2287.44 ft^2, the lateral area of the roof:≈1580.58 ft^2
Step-by-step explanation:
The area of the roof is computed by the equation of the area of a cone:
A = πr(r + 
)
(r: radius, h: height, πr^2 is the area of the base of the cone, πr is the lateral area of the cone). So:
A = 
≈ 2287.44 ft^2.
As I stated earlier, the lateral area of the roof can be computed:
A
=
≈ 1580.58 ft^2.
Yes☺
you are right 7 times 6 is 42 and 7 times. 8 is 56
