Use the expression 8a + 16c. Part a
Factor the expression using the GCF.
part b
What is the value of the expression
when a = -5 and c = -1?

PA) 8

PB) 45

Step-by-step explanation:

PA) Find the prime factors of each term in order to find the greatest common factor (GCF).

8

PB)

Step 1:

(8 x 5) + (16 x -1)

Step 2: Multiply

40 + 15

Step 3: Add

45

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
