Jessica’s friend tried to find the side length of a square garden, but made a mistake:
24 x + StartFraction 12 over 13 EndFraction = 4 (6 x + StartFraction 12 over 13 EndFraction) = Side length = 6 x + StartFraction 12 over 13 EndFraction
Can you identify and correct her error?
Answer:
I will put the answer below, but here is a tip:
Use PEMDAS. PEMDAS IS THIS:
P ( ) parenthesis
E y+x exponents
M x multiplication
D ÷ division
A + addition
S - subtraction
Key:
Property used=PU
Step-by-step explanation:
Part A:
18= 6x(2x-3) PU=( ), y+x, x, & -
Part B:
8+3b-1 PU= y+x, +, & -
Part C:
=12 PU= =
Part D:
14+3n=8n-3x(1-4) PU= ( ), y+x, x, +, & -
Part E:
22x+11-4x-7 PU= y+x, +, & -
Complete the square: x^2 + 24x = 17
Identify the coefficient of x. It is 24. Take half of that coefficient: 24/2 = 12.
Now add the square of 12 to both sides of x^2 + 24x = 17
x^2 + 24x + 144 = 17 + 144
Write in factored form:
(x + 12)^2 = 161
Taking the square root of both sides:
x+12 = plus or minus
