Answer:
Option C.
Step-by-step explanation:
The given expression is
We need to find the factored form of the given expression.
The given expression can be rewritten as
It is clear that is common.
Taking out common factors, we get
It is the factored form of the given expression.
Hence, the correct option is C.
Answer:
length and width of the photo are: w = 6cm l = 8cm
Step-by-step explanation:
Area = 168cm^2
Area = w • l
168 = (x + 3 + 3) • (x + 2 + 3 + 3)
168 = (x + 6) • (x + 8)
expand
168 = x^2 + 14x + 48
subtract 168 from both sides
0 = x^2 + 14x - 120
simplify
0 = (x - 6) • (x + 20)
x = 6 or -20
since we are dealing with a measurement of a physical object x > 0
x = 6cm
w = x = 6cm
l = x+2 = 8cm
False, pictures are used in picture graphs or pictographs
