Answer:
AC = 38
Step-by-step explanation:
A mid point divides a line in 2 equal parts. That means that one segment is equal to the other.
6x + 1 = 3x + 10 Subtract 3x from both sides
6x-3x + 1 = 3x -3x + 10 Combine
3x + 1 = 10 Subtract 1 from both sides
3x + 1 -1 = 10 - 1
3x = 9 Divide by 3
3x/3 = 9/3
x = 3
6x + 1 = 6*3 + 1 = 19
3x +10= 3*3 + 10 = 19
Both segments are 19 units long
AC = 19 + 19 = 38
Subtract x^10 from both sides. add 17 to both sides. divide both sides by 7.3 take root and the answer should be x=1.08821, -1.08821
Answer:
(r-12)(r+1). if r=2, then plug it into the expression. (2^2)-11(2)-12 = -30

Answer:
4(x + 5)(x - 3)
Step-by-step explanation:
Given
4x² + 8x - 60 ← factor out 4 from each term
= 4(x² + 2x - 15) ← factor the quadratic
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)
The factors are + 5 and - 3 , since
+ 5 × - 3 = - 15 and + 5 - 3 = + 2, then
x² + 2x - 15 = (x + 5)(x - 3)
Then
4x² + 8x - 60 = 4(x + 5)(x - 3) ← in factored form
