You have the following equation:
11h - (2h -1) = 118
In order to solve for h the previous equation you proceed as follow:
11h - (2h -1) = 118
elminate parenthesis by takin into accoun the multilpication of signs
11h - 2h + 1 = 118 simplify similar terms and subtract 1 both sides
9h = 117 divide by 9 both sides
h = 117/9
h = 13
Hence, the solution to the given equation is h = 13
Answer:
a = 5
Step-by-step explanation:
According to the factor theorem, if x + 2 is a factor, then by dividing the polynomial by the binomial, we are meant not to have a remainder
In this case, the remainder would be zero
So, if we set the binomial equals zero and substitute the x-value into the polynomial, we are supposed to have 0
So we have this as;
x + 2 = 0
x = -2
-2^3 -2(-2)^2 -2(a) + 6 = 0
-8-8-2a + 6 = 0
-16 + 2a + 6 = 0
2a -10 = 0
2a = 10
a = 10/2
a = 5
Because all 3 sides are given for both triangles you can use the SSS theorem
