Answer: 9. x=-3/2 10. x=2
x= 5/2 x=5/3
Step-by-step explanation:
9. Factor the equation:
How: put 4x^2 in the bottom left box and -15 in the upper right box.
then multiply 4x^2 x -15 = -60x^2 and put your answer in the top center box of the diamond.
Put the -4x from the equation in the bottom box. Then list out factors that multiply to the top box (-60x^2) and add to the bottom box (-4x) The two factors are -10 and 6
-10 x 6 = -60
-10 + 6 = -4
Put -12x and -5x in the remaining white boxes and find what numbers multiply to each.
I attached a picture. The colored dots correspond with each other.
Eg: Orange dot x orange dot = number in white square
Now you get the two factors (2x+3)(2x-5)
Set both of these equal to 0 and solve
0=2x+3 0=2x-5
x= -3/2 x= 5/2
Do the same for the other problem
PEMDAS Solve the parentheses first so 9+4=13. Then do the division so 6/6=1. Now the equation is 37- 13+ 1. Then work left to right. 37-13= 24 then 24+1=25.
The correct answer to 38 is B

Answer:
Step-by-step explanation:
1. x - 2 = 10
x = 10 + 2 = 12
2. 40 = 5x
40/5 = x
x = 8
3. x/2 = 8
Multiply by 2 on both sides
x = 16
4. x + 14 = 24
x = 24 - 14 = 10
5. x + 2 = 10
x = 10 - 2 = 8
6. x/8 = 1
Multiply by 8 on both sides
x = 8
No 2 5 and 6 is the correct answer
