Answer:
C) The sample does not accurately represent the population
Answer:
44 cm²
Step-by-step explanation:
Ar(big rect.) = (4+4)×(4+3)
= 8×7
= 56
Ar. of small rect. = 4×3 = 12
Area of X = 56-12
= 44 cm²
Answer:
length of each is 12 meters
Step-by-step explanation:
for larger rectangle:
let '2w' = length
let 'w+4' = width
2w(w+4) = 120
2w² + 8w - 120 = 0
simplify by dividing each term by 2 to get:
2(w² + 4x - 60) = 0
(w-6)(w+10) = 0
width cannot be negative 10 and is therefore equal to 6
since length is '2w' then length is 2(6) which is 12

Next time, please include the directions. Here the directions would state, "Solve the following linear equation for x."
15-2x-8-3x=-x-12+4x+43
First: combine like terms: 15 - 8 - 2x - 3x = 3x + 31 => 7 - 5x = 3x + 31, or
8x = 24.
Next, solve the above result for x: x = 24/8 = 3
The solution is x = 3.
