I hope this helps you
square root of (4x+41)=x+5
4x+41>=0
x >= -10.25
(square root of4x+41)^2=(x+5)^2
4x+41=x^2+10x+25
x^2+6x-16 =0
x +8
x -2
(x+8)(x-2)=0
x= -8
x= 2 extraneous
Answer:
Step-by-step explanation:
<u>Area of the top section:</u>
- A₁ = x*(x - x + 3) = x*3 = 3x in²
<u>Area of the bottom section:</u>
- A₂ = (x + 4)(x - 3) = x² + x - 12 in²
<u>Total area:</u>
- A = A₁ + A₂ =
- (3x) + (x² + x - 12) in²
Correct choices are C and D

Step-by-step explanation:
<u>Step 1: Define</u>
x/5 - 1 = 10
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 1 to both sides: x/5 = 11
- Multiply 5 on both sides: x = 55
