Answer:
Sum = 4 + 5 = 9
Step-by-step explanation:
Equation
2*(x - 2)(x-2) = (x - 3)(x + 4)
Solution
2*(x^2 - 4x + 4) = x^2 + 4x - 3x - 12
2x^2 - 8x + 8 = x^2 +x - 12 Subtract the right side from the left
x^2 - 9x + 20 = 0
(x - 4)(x - 5) = 0
The possible values for x are
x - 4 = 0
x = 4
x - 5 = 0
x = 5
Check
(4 - 2)^2 = (4) = 4
(x - 3)(x + 4) = (4 - 3)(8) = 8
This checks
(5 - 2)^2 = 3^2 = 9
(5 - 3)(5 + 4) = 2 * 9 = 18
What is the slope of the line: y=-1/2x+3?
y = mx + b where m = slope
so y=-1/2 x+3 ; m = -1/2

Answer: 2 + 2 x 10 = 22
10 x 100 (?) = 1,000
1,000 x 10,000 (?) = 10,000,000
Step-by-step explanation:
For A, (2 + 2 x 10), you need to multiply first, 2 x 10 = 20. Then, you must add 2, which equals 22.
For B, which is (10 x 100, I think) you will multiply the top number by the bottom number, let’s say 100 is on the top. You will line thin up, 100 x 10. You will need to multiply 0 times 100, which is 000. You will then need to move over a slot, and then times 100 by 1. After doing that then you add your numbers, which gives you 1,000.
For C you do the same steps you used for B.
