What is the next step in solving 0 = x2 + 6x – 10 by completing the square, after you cut 6 in half?
2 answers:
Answer:
see below
Step-by-step explanation:
0 = x^2 + 6x – 10
Add 10 to each side
10 = x^2-6x
Take the coefficient of x
-6
Divide by 2
-6/2 =-3
Square it
(-3)^2 =9
Add 9 to each side
10+9 = x^2-6x+9
We use -3 for the square term
19 = (x-3)^2
Take the square root of each side
±sqrt(19) = x-3
Add 3 to each side
3±sqrt(19) = x
Answer:
Step-by-step explanation:
0 = x^2 + 6x – 10
Add 10
10 = x^2-6x
-6
Divide by 2
-6/2 =-3
Square it
(-3)^2 =9
10+9 = x^2-6x+9
-3 for the square ter
19 = (x-3)^2
(19) = x-3
Add 3 to each side 3to(19) = x

Answer:
12 square feet
Step-by-step explanation:
The shape of the top of the desk is a trapezoid.
A = (b1 + b2)h/2
A = (5 ft + 3 ft)(3 ft)/2
A = (8 ft)(3 ft)/2
A = 24 ft^2/2
A = 12 ft^2
