Answer:
3x^7+2x^6-5x^5
Step-by-step explanation:
(3x^7-4x^5+3)+(2x^6-x^5-3)
3x^7-4x^5+3+2x^6-x^5-3
3x^7+2x^6-4x^5-x^5+3-3
3x^7+2x^6-5x^5
Answer: B. 8 x 10^3
Step-by-step explanation:
At least they admitted this is algebra not geometry. You'll get the same question next year but they'll call it geometry.
The area is the product of the sides:
We just distribute and collect terms:
Answer: 3rd choice
Answer:
y = 8.5
Step-by-step explanation:
7y - 4 = 9y +13 - 4y
First arrange to combine like terms.
7y - 4 = 9y - 4y + 13
7y - 4 = 5y + 13 Subtract 5y from each side
7y - 5y - 4 = 5y - 5y + 13
7y - 5y - 4 = 13
2y - 4 = 13 Add 4 to each side
2y - 4 + 4 = 13 + 4
2y = 13 + 4
2y = 17 Divide each side by 2
2y/2 = 17/2
y = 17/2 or 8 or 8.5
Answer:
48
Step-by-step explanation:
If EG=8, OE=4
x/12=4
x=4(12)
x=48
