The expression "negative 8 minus 7" can be simplified as -8 - 7. To subtract a positive number from a negative number, you can add the opposite. Therefore, -8 - 7 is the same as -8 + (-7), which equals -15.
69 is an equivalent expression.
The value of the expression 8 is always 8, whatever f is.
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
(x-8)(x+8)
It is: 8+7 = 15
15/8 or 1 7/8 or 1.875

The expression 9+5 is equivalent.
2(3x + 4) = 6x + 8 3(x - 5) = 3x - 15 6x + 8 - 3x + 15 = 3x + 23
Combine like terms: 8w-6w = 2w -8-7 = -15 6w4w = 24w2 So, your expression is now: 24w2 + 2w - 15
No because 8/15 is bigger than 7/14
5/(8 + √7) = (40 - 5√7)/57 is the rationalised equivalent.
7
The expression -28x+35 is equivalent to 7y(-4x+5)
8/9 = 0.888888(repeating)
