Answer:
Step-by-step explanation:
Front and back
Givens
base = 6 feet
height = 2
Formula
Area = 1/2 B * h
Area = 1/2 * 6 * 2
Area = (2) 1/2 * 12
Area = 12 square feet for both front and back
Base
The base is a rectangle. A rectangle has the formula of Area = L*w
Givens
L = 10 feet
W = 6 feet
Area = 10 * 6 = 60
Left roof
The left roof is also a rectangle. Area = L*w
Givens
L = 10 feet
W = 3 feet
Area = 3 * 10 = 30 feet^2
Right Roof
The right roof is a rectangle. Area = L*w
Givens
L = 10 feet
w = 4 feet
Area = 4 * 10 = 40 ft^2
Total area
Total Area = right roof + left roof + Base + front and back
Total Area = 40 + 30 + 60 + 12
Total Area = 142 feet ^2

Step-by-step explanation:
To find the product of the matrices: ![\left[\begin{array}{cc}4&2\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D4%262%5C%5C%5Cend%7Barray%7D%5Cright%5D)
× ![\left[\begin{array}{cc}-2&5\\7&-1\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-2%265%5C%5C7%26-1%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Multiply rows of the first matrix by the columns of the second matrix.
(4 × (–2) + 2 × 7 4 × 5 + 2 × (–1))
After simplifying this, we get the product
Hence, × =
Answer:
4.5 so 5
Step-by-step explanation:
36 divided by 8= 4.5
AB = X^2(3X +2)
C^2 = (x - 3)^2
AB - C^2 = 3x^3 + 2x^2 - (x^2 - 6x + 9)
= 3x^3 + x^2 + 6x - 9
