Answer:
32
Step-by-step explanation:
Given
-x (y + z)
If y = -3
x = 4 and
z = -5
Substitute the respective values into the expression
-(4) (-3 + -5)
Positive negative when combined gives negative
-4 ( -3 - 5)
Simplify the bracket
-4 (-8)
-4 x -8
Negative negative gives positive
48 out of 50 correct answers
follow these steps:
1) y-4=7x^2
2) (y-4)/7 = x^2
so you must inverse x and y names:
4
Take out a 2 to begin with.
2(25x^2 - 36) This is the difference of squares (inside the brackets). Factor.
2*(5x - 6)(5x + 6)
There is a 55% chance that it won't rain.
