Question 12. ).
Solve:
- 5x + 5 + 4x^2 = 0
Simplify both sides:
4x^2 - 5x + 5 = 0
Step 2.): Use Quadratic Formula:
a = 4, b = - 5, c = 5
x = - b +/- sqrt b^2 - 4ac/2a
x = - ( - 5) +/- sqrt ( - 5)^2 - 4(4)(5) / 2(4)
x = 5 +/- sqrt - 55/8

Hope that helps!!!!! : ) sorry couldn't help with the rest. My brain has to rejuvenate, at a stand still right now.
Answer:
33 feet
Step-by-step explanation:
Given
1 inch= 12 feet
we have to find actual length of wall when length of wall on drawing is 2 3/4 inches
to do that lets multiply LHS and RHS of above equation with 2 3/4
2 3/4 inches = (2*4 +3 )/4 = 11/4 inches
1 inch* 2 3/4= 12 feet* 2 3/4
1*11/4 inches = 12*11/4 feet = 33 feet
Thus, actual length of wall is 33 feet.
I would answer about 1/3 cups
