Answer:
16'1"
A) 6' + 5' + 3' = 14'
B) 10" + 4" + 11" =25" = 2'1"
A+B= 16'1"
1 Feet = 12 Inches
Answer:
x = - 2, x = - 
Step-by-step explanation:
Given
5x² + 1 = - 13x - 5 ( add 13x - 5 to both sides )
5x² + 13x + 6 = 0
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term
product = 5 × 6 = 30 and sum = 13
The factors are 10 and 3
Use these factors to split the x- term
5x² + 10x + 3x + 6 = 0 ( factor the first/second and third/fourth terms )
5x(x + 2) + 3(x + 2) = 0 ← factor out (x + 2) from each term
(x + 2)(5x + 3) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
5x + 3 = 0 ⇒ 5x = - 3 ⇒ x = - 
The incorrect answer is B.
All you have to do is plug in x to the formulas and see if the are equal.
4x - 2 = 3x + 6
4(8) - 2 = 3(8) + 6
30 = 30
CORRECT
The second is not only not equal, but it is the wrong kind of formula for what you are trying to prove there.
Hope that helps!
