Answer:
7,11
Step-by-step explanation:
The width is x. x+4= the length. The area is side times side, so it’s
x × (x+4) = 77
We can simplify this to:
x × x + x × 4 = 77
x^2 + 4x = 77
x^2 + 4x - 77 = 0 This is a quadratic equation. So we can solve using the quadratic formula:
x =
->


That’s the positive solution and that’s x, the width. So the width is 7 and the length is 7+4=11

Answer:
3x+9
Step-by-step explanation:
since p(x) means p multiplied by x and the answer is 3x it means p=3 so 3(x+3) you multiply 3 by x which is 3x and 3 times 3 which is 9 so 3x+9

Answer:
yes
Step-by-step explanation:
In front of every variable there is an invisible one which is being multiplied by the variable. This doesn't affect the variable because anything times one is still itself. The most common usage of the one is when combining like terms such as x+x. Since the equation is really 1x+1x, it would be 2x.
