Answer: C) Cannot be done
Taking the square root of a negative number is not possible unless you involve complex numbers. If your teacher has not introduced that topic yet, then you just simply say "cannot be done" or something along those lines.
Answer:
Step-by-step explanation:
The side that is parallel to BC is EF
Find the slope of EF:
Easiest way is just put the formula in point-slope form and simplify.
Let's use point F, which is (6,2)
Simplify:
Add 2 on both sides:
Hope this helped
Answer:
Step-by-step explanation:
(a - b)² = a² + 2ab + b²
Area of square frame =side²
= (2b - 1)²
= (2b)² - 2*2b * 1 + 1²
= 4b² - 4b + 1
Answer:
42.75
Step-by-step explanation:
area of one piece, length x width: 3 x 4 3/4
14.25
area of 3 pieces: 14.25(3)= 42.75
Answer:
Step-by-step explanation:
<u>Given equation</u>
<u>Solving for h</u>
- A=1/2(B₁+B₂)h
- 2A = (B₁+B₂)h
- 2A/(B₁+B₂)= h
- h = 2A/(B₁+B₂)
