B, or at least I'm pretty sure
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
Answer:
6x+7y is B
6x+14y is C
(2x+3)+4(x+y) is F
(2x+4y)+2(2x+5y) is G

Answer:
85.4054%
Step-by-step explanation:
3.16/3.7 × 100
Divide.
0.854054 × 100
Multiply.
= 85.4054
-1-7x-6(-7-x)=36
-1-7x+42+6x=36
41-7x+6x=36
41-x=36
-x=36-41
-x=-5
Answer: x=5
