Answer:
303.63 sq inches
Step-by-step explanation:
We need to find the area of the two rectangles he cuts and add them together.
The area of a rectangle is given as:
A = L * B
The first rectangle is 16 inches × 12 1/4 inches. Its area is:
A = 16 * 12 1/4 = 16 * 49/4 = 196 sq inches
The second rectangle is 10 1/2 inches by 10 1/4 inches. Its area is:
A = 10 1/2 * 10 1/4 = 21/2 * 41/4 = 107.63 sq inches
The total square inches of construction paper that he needs is:
196 + 107.63 = 303.63 sq inches
Answer:
angle 1 is equal to 40°
Step-by-step explanation:
angles 1 and 2 are congruent due to alternate interior angles of parallel lines. This means that 2x+20=3x+10, solving this leaves us with x=10. Since angle 1 = 2x +20 and x=10, solve to get 2(10)+20 =20+20 = 40
2x^2 + 3x + 8 = 0
Answer: B) -3 + I √55 over 4.
Answer:
x = 117
Step-by-step explanation:
Given
11 - 
= 0 ( subtract 11 from both sides )
- = - 11 ( square both sides )
(- )² = (- 11)²
x + 4 = 121 ( subtract 4 from both sides )
x = 117
