Answer:
8x² + 6x - 35
Step-by-step explanation:
A = (2x + 5)(4x - 7)
Front: 2x * 4x = <em>8x²</em>
Outside: 2x * (-7) = <em>-14x</em>
Inside: 5 * 4x = <em>20x</em>
Last: 5 * -7 = <em>-35</em>
Add up: <em>8x² - 14x + 20x -35</em>
Simplify: 8x² + 6x - 35
Answer:
x = -64
Step-by-step explanation:
Step 1: Write out equation
9 - 3/4x = 57
Step 2: Subtract 9 on both sides
-3/4x = 48
Step 3: Multiply both sides by -4/3
x = -64
Answer:
3/10 + 4/10
1/2 + 1/5
1/10 + 3/5
Step-by-step explanation:
3/10 + 4/10 = 7/10 (add numerator and keep denominator)
1/2 + 1/5 = 5/10 + 2/10 = 7/10 (use equivalent fractions)
1/10 + 3/5 = 1/10 + 6/10 = 7/10
