Answer:
x² + 6
Step-by-step explanation:
Given
(4x² - 6x + 8) - (3x² - 6x + 2) ← distribute by - 1
= 4x² - 6x + 8 - 3x² + 6x - 2 ← collect like terms
= x² + 6
Answer:
y=2
Step-by-step explanation:
15y+5y-19y+2=4
y+2=4 Add similar elements
y+2-2=4-2 Subtract 2 from both sides
y=2 Simplify
A=(pi)d
158.368=3.14d
d=50.436
r=25.218
Answer:
-10
Step-by-step explanation:
The equation would be -8 - (-10) = 2. When subtracting a negative, you are actually just adding a positive. It's like the two negative signs cancel each other out, so it would look more like -8 + 10 = 2. For the answer box, just put -10.
