A straight line is 180° so....
9x+24 +6x - 24 = 180
15x=180. ( because you have to combine like terms.
X= 12
x = ×-3/4
because you hace the variable x and you do not know the number of fruit snacks he ate and you need to have the same variables to properly find the answer.
the correct question is
What values of b satisfy 3(2b+3)^2 = 36
we have

Divide both sides by 

take the square root of both sides





therefore
the answer is
the values of b are


Answer:
k = 25
Step-by-step explanation:
(2x - sqrt(k) )^2 Expand this as a binomial
4x^2 - 4x*sqrt(k) + k The middle term must be -20x Solve for k so it is
-4xsqrt(k) = - 20x Divide by -4x
sqrt(k) = -20x/-4x Do the division
sqrt(k) = 5 Square both sides
k = 25
Answer:
D. -x2 + 2x -3
Step-by-step explanation:
the first step is we open all the brackets then it will be :
x2 - 3x - 2x2 + 5x - 3
= x2 - 2x2 - 3x + 5x - 3
= -x2 + 2x -3
