Answer:
(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);
Step-by-step explanation:
formula to find area is L* W = A ; meaning length multiplied by width equals to the area.
21.
using the formula to find area...
l*w=a
(7x+2)(3x-1) would be your answer
btw, don't put the "=a" at the end, since it's an expression :))
22.
since the problem states that it's a square, you can just say either...
(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts
Here’s the first few and you can do the rest with the same principles. If you need more help with the last ones then let me know
we can always find the slope of any line by simply using two points on the line, say let's use (3,4) and (-1,2)

Answer:
The absolute value is 7.
Step-by-step explanation:
Because when a number has two lines between it you always make it positive.
