Answer:
i jist need ze points really quick sowy:(
The opposite of multiplication is division, so if you take the signaler number after the equal sign divide it by the number before and it will give you the missing number like this:
(I'm only going to do a few and then you try it. I can check it when you are done)
6 x ____ = 60 <<<Divide 6 by this number
60 ÷ 6 = 10
6 x 10 = 60
140 ÷ 10 = 14
140 = 14 x 10
500 ÷ 50 = 10
50 x 10 = 500
Hope this helps!

Answer:
x = 4 or x = -2
Step-by-step explanation:
Solve for x over the real numbers:
x^4 - 9 x^2 - 22 x - 24 = 0
The left hand side factors into a product with three terms:
(x - 4) (x + 2) (x^2 + 2 x + 3) = 0
Split into three equations:
x - 4 = 0 or x + 2 = 0 or x^2 + 2 x + 3 = 0
Add 4 to both sides:
x = 4 or x + 2 = 0 or x^2 + 2 x + 3 = 0
Subtract 2 from both sides:
x = 4 or x = -2 or x^2 + 2 x + 3 = 0
Subtract 3 from both sides:
x = 4 or x = -2 or x^2 + 2 x = -3
Add 1 to both sides:
x = 4 or x = -2 or x^2 + 2 x + 1 = -2
Write the left hand side as a square:
x = 4 or x = -2 or (x + 1)^2 = -2
(x + 1)^2 = -2 has no solution since for all x on the real line, (x + 1)^2 >=0 and -2<0:
Answer: x = 4 or x = -2
Answer:
The value of x is 12 is not true.
Step-by-step explanation:
Since the line intersecting them are at a diagonal, it is not possible that the other of the lines both equal 115. Everything else in the choices is true.
