Do distributive property first
4x + 8 = 28
move the 8 over
4x = 20
divide by 4
x = 5
Answer:
9x+8 and 3x+5.
Explanation:
Let the first polynomial = 9x + 8
Let the second polynomial be a+b

Similarly:

Thus, the second polynomial = 3x+5
Therefore, the two polynomials whose difference is 6x+3 are 9x+8 and 3x+5.

Answer:
A. Not a function
B. function
C. function
D. not a function
Step-by-step explanation:
A is not a function because it has more than one of the same input ( x value)
B is a function because it does NOT have more than one of the same input (x value)
C is a function because it does NOT have more than one of the same input (x value)
D is not a function because it has more than one of the same input ( x value)
Hope this helps.
Answer:
w = 3
l = 10
Step-by-step explanation:
l = 4w-2
P = 26cm
P = (l + w) × 2
26 = (4w-2+w) ×2
26 = (4w + w - 2) × 2
26 = ( 5w - 2 ) × 2
26 ÷ 2 = 5w -2
13 = 5w - 2
13 + 2 = 5w
15 = 5w
w = 3
l = 4w - 2
l = (4 × 3) -2
l = 12 - 2
l = 10
