What is the simplified expression for the expression below? 7(x – 4) – 3(x + 5)4x – 434x + 14x – 134x – 9

4x-43

Step-by-step explanation:

Here we have to simplify the expression 7(x – 4) – 3(x + 5)

In order to do so we first open the two brackets using distributive laws.

7(x – 4) – 3(x + 5)= 7*x-7*4-3*x-3*5

= 7x-28-3x-15

Now we bring the terms containing the x together and the terms not containing x together

= 7x-3x-28-15

we simplify them

= 4x-43

Hence

7(x – 4) – 3(x + 5)=4x-43 is the simplified expression

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
