Answer:
you need to subtract
Step-by-step explanation:
Answer:
4x^2-16x-20
Step-by-step explanation:
(x-5)(x+1)=x^2-5x+x-5=x^2-4x-5
leading coefficient=4
which means that 4(x^2-4x-5)=4x^2-16x-20 is the answer.
Pretty sure it’s the second answer
210/360 = 7/12, meaning the shaded area is 7/12 of the entire circle.
The circle has radius 12 in, so its total area is π (12 in)^2 = 144π in^2.
Then the area of the shaded region is 7/12 of this, or
7/12 * (144 π in^2) = 84π in^2 ≈ 263.89 in^2
Answer:
2x^2=3x+2
2x^2-3x-2=0
(x-2)(x+1/2)=0
x=2 or x=-1/2
The sum of 2 solution 2+-1/2=3/2
