Answer:
D 2x(3x+4) + 1(3x+4)
Step-by-step explanation:
(2x+1) (3x+4)
We need to FOIL
First 2x*3x = 6x^2
Outer 2x*4 = 8x
Inner 1*3x =3x
Last 1*4 =4
Add them together
6x^2 +8x+3x+4
Combine like terms
6x^2 +11x+4
This process is simply taking 2x (3x+4) and adding 1 (3x+4)
2x(3x+4) + 1(3x+4)
I hoped you passed the assignment
Step-by-step explanation:
Answer:
= 2.5 Pounds per Week
Showing Work
This is a fraction equal to
25 Pounds ÷ 10 Weeks
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 10
25 Pounds ÷ 10
10 Weeks ÷ 10
=
2.5 Pounds÷1 Week
=
2.5 Pounds
__________
Week
= 2.5 Pounds per Week
Answer:
B
Step-by-step explanation:
mean = average. to find it, add all terms, and then divide by the number of terms.
find the mean of group a:
(1+1.5+3+3.2+2.8+1.5+1.8+2.5+2.2)/9 = 2.16
find the mean of group b:
(2+2.5+3.2+3+1.8+2.4+3+1.5+1/8)/9 = 2.1694
group b is larger.
answer = b
I am confused. I need more context.
