Answer:
(x + 3)(x + 5)
Step-by-step explanation:
The given expression is x^2 +8x + 15
Now find the factor of 15 such that when you add the factors, we have to get 8
The right factors of 15.
5 * 3 = 15
5 + 3 = 8
The right factors are 3 and 5.
x^2 + 8x + 15 = (x + 3)(x + 5)
Therefore, x^2 + 8x + 15 = (x + 3)(x + 5)
Thank you.
<span>Your Answer: D
Why....
You can make equations out of the information
Let L be Lin, G be Greg, and F be Fran
L = 4 + G ---"Lin sold 4 more shirts than Greg"
F = 3L ---"Fran sold 3 times as many shirts as Lin"
F + G + L = 51 ---"In total the three sold 51 shirts"
Use F + G + L = 51
Substitute the equations in for F and L (because you need to know the G) like this....
(3L) + G + (4+G) = 51
You still have a variable besides G in there... you can use the L= 4+G and substitute again so that there are only G's
( 3(4+G) ) + G + (4+G) = 51 ---- SIMPLIFY :D
( 12 + 3G ) + G + 4 + G = 51
12 + 3G + G + 4 + G = 51 ---Combine like terms
16 + 5G = 51 </span>
Answer:
0.01
Step-by-step explanation:
If you convert 10 into a decimal it's just 0.1, multiply 0.1 by itself only one time because the exponent is 2 and you get 0.01
Answer:
5x^2+2x-432
Step-by-step explanation:
15x^2+x-215×2+x−2
=15x^2+x-430+x−2
=15x^2+x+x-430-2
=15x^2+2x-432
Perform the indicated division, if any.
Rate: (500 miles)/(20 hours)
Unit rate: (500/20) miles/hour = (25 miles)/(1 hour) = 25 miles/hour
A unit rate is a rate with one unit in the denominator.
