Since the first term in the equation is
, you know that each group you make will have to have an x in it. Now, you need to figure out what times what equals 7 and adds up to 8. You can list all of the numbers that multiply to seven until you find the right numbers.
-1 x -7
1 x 7
1 and 7 add to eight and multiply to seven, so those will be the numbers in your groups. This makes your factored groups
(x + 1)(x + 7).
Answer:
n = -2
Step-by-step explanation:
4n + 12 = 4
Subtract 12 from both sides.
4n = -8
Divide both sides by 4.
n = -2
Answer:
x=4
Step-by-step explanation:
3x+6=2x+10
x+6=10
x=4
Answer:
no its a scalene triangle
Step-by-step explanation:
Hello There!
7d² + 10
7(3)² + 10
3² = 9
7 x 9 = 63
63 + 10 = 73
Hope This Helps You!
Good Luck :)
