(4x+3)(2x-5) = 8x²-14x-15

Step-by-step explanation:

Given,

(4x+3)(2x-5)

To find the value of the given multiplication.

Formula

(a+b)(c+d)

Whitney left school and drove 7 miles to meet her mother at a restaurant. Her mother left at the same time and drove 8 miles, tr

Tresset [83]

Answer:

Step-by-step explanation:

If Whitney was driving x speed, her mother was driving x+5. Multiply that by the distance each traveled, and you have an equation that looks like this:

8(x+5) = 7(x)

Simplify it and you get:

8x + 40 = 7x

Now solve regularly:

8x-8x + 40 = 8x - 7x

40 = 1x

40 = x

Whitney's speed: 40

Her mother's speed: 45
