Answer:
44x+49 is a factor of 44x+49
Step-by-step explanation:
4 x 4 = 16x
16x + 28x = 44x
a variable cannot be added with a number without a variable
so 44x + 49 is the answer
153.86 is the answer because the formula is Pi times radius squared. So, the equation would be 3.14X7^2=3.14X49=153.86
THE SLOPE IS -2
if we have the coordinates of two points on a line, we can find the slope with this formula:

so the slope is

the answer is -2
good luck
