Answer:
Step-by-step explanation:
<u>Given sides of a rectangle</u>
- Length: l =4 − 7(3x + 4y)
- Width: w = 3x(−2y)
<u>Perimeter of rectangle</u>
<u>Using the given values</u>
- P = 2( 4- 7(3x + 4y) + 3x(-2y)) =
- 2( 4 - 21x - 28y - 6xy) =
- 8 - 42x - 56y - 12xy
Answer:
x
Step-by-step explanation:
This is like y = 6(x), most always the y is dependent on x since it changes based on what x is, so x is independent, and y is dependent
The change of base rule says

If b = 1, then we will have


which is NOT possible. We cannot divide by zero. So this is why b = 1 is NOT allowed.
C, 125. Hope I helped.
btw, u gotta do 35+30+25+20+15
