Step-by-step explanation:
Answer:
x = ±6
Step-by-step explanation:
Step 1: Write out equation
x² + 7 = 43
Step 2: Subtract 7 on both sides
x² = 36
Step 3: Square root both sides
√x² = √36
x = ±6
Collect like terms
6.5x-4.5x = 6+10
2x = 6+10
Divide both sides
2x = 16
X= 8
Answer: 20x + 20
Step-by-step explanation: In this problem, the 5 "distributes" through the parentheses, multiplying by each of the terms inside.
So we have 5(4x) + 5(4) which simplifies to 20x + 20.
