Find the dimensisions of each matrix product p1×5* q5×1
a. 1×5
b. 1×1
c. 5×1
d. 5×5
e. n it defined

a negative exponent is translated as follows:

so, we have

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
