10 ft +12 ft =22ft so it 22 ft.
22ft-4ft is 18ft.
18 ft is the answer
Yes, (3, 2) is a solution to y = 2x - 4. (:
She regrouped the numbers instead of multiplying like 8b(2b-r) -4r(2b-r).
15 × 60 = 900
900 × 22 = 19800
The answer is 19800 screws
Answer:
x=4
Step-by-step explanation:
√x+12=x
x+12=x2(Square both sides)
x+12=x2
x+12−x2=x2−x2(Subtract x^2 from both sides)
−x2+x+12=0
(−x−3)(x−4)=0(Factor left side of equation)
−x−3=0 or x−4=0(Set factors equal to 0)
x=−3 or x=4
x=−3(Doesn't work in original equation)
x=√x+12
