Answer: a^2+3a+2
Step-by-step explanation:
if you do the distribution method and do (a*a)+(a*2)+(1+a)+(1*2)=(a^2)+(2a)+(a)+(2)
which you get a^2+3a+2

Answer:
You just find the volume of the cup and subtract the volume of the froth (whatever that is).
V(cup) = pi * r^2 * h
...........= pi * 4.3^2 * 11.2
...........= 650.586cm^3
V(froth) = pi*r^2*h
............= pi*4.3^2*0.4
.............=23.232cm^3
V(hot chocolate) = V(cup) - V(froth)
.........................= 650.586 - 23.232
.........................= 627cm^3

The school show choir is holding a car wash to raise $350 for
new costumes. After spending $30 on supplies, the students will
wash cars for donations of $6 each.
This situation can be modelled by the inequality 6C + 30 > 350,
which has the solution c> 53.33. What is the best way to
interpret this solution?
A. Show choir needs $53.33 to meet their goal.
B. Show choir should have spent another $53.33 on supplies.
C. At least 54 show choir students must participate in the car
wash.
D. Show choir needs to wash at least 54 cars.
Answer:
D.
Step-by-step explanation:
It’s the only option that makes sense. Option A. Is invalid because they need to make $350. Option B. Is just purely invalid and has no context to support the theory. C. Is possible, but we can have students wash more than one car, so we don’t need fifty four kids.
D. Is your answer.
Hope this helped!!

Answer:
Area = 201 1/4 yard^2
Or in decimal form: 201.25 yard^2
Step-by-step explanation:
First convert the mixed numbers into improper fractions or even decimal form so it is easier to operate with them:
Base = 11 1/2 yards = 23/2 yards = 11.5 yards
Height = 17 1/2 yards = 35/2 yards = 17.5 yards
Use the formula for the area of a parallelogram:
Area = Base x Height
which in our case give:
Area = 23/2 x 35/2 = 805/4 yard^2 = 201 1/4 yard^2
Or in decimal form: 201.25 yard^2
the range of the quedractic function is {y|y
well I have no idea what that means but I hope you find your answer

plz help and answer ASAP with full working
Answer:
Step-by-step explanation:
Gabriela's mass : Pierre's mass = 3 : 8
Gabriela's mass = 3x
Pierre's mass = 8x
Total mass= (1/4) of total height
3x + 8x = [tex]\frac{1}{4}(110 + 154)[/tex]
11x = [tex]\frac{1}{4}*264[/tex]
11x = 66
x = 66/11
x = 6
Gabriela's mass = 3x = 3*6 = 18 Kg
Pierre's mass = 8x = 8*6 = 48 kg

15-24 divide3 •2+13= Simplify the expression
Answer:
7
Step-by-step explanation:
Given: 15 - 24 divide 3 . 2 + 13 =
The expression can be solved step-wisely so as to determine the appropriate answer.
So that,
15 - 24 = -9
-9 ÷ 3 = -3
-3 . 2 = -6
-6 + 13 = 7
The required answer to the expression is 7.
Thus,
15 - 24 divide 3 . 2 + 13 = 7
what is 2-2? i dont know
Answer:
2-2 = 0
Step-by-step explanation:
2 is a positive number
While the second 2 is a negative 2
(-2)
so a positive and a negative number can cancel eachother out
Therefore the answer is 0 since they are both 2 :)
Let Ln denote the left-endpoint sum using n subintervals and let Rn denote the corresponding right-endpoint sum. In the following exercise, compute the indicated left and right sums for the given function on the indicated interval.
L4 for f(x)=1/x−1; [2,3]
Answer:
[tex]L_4=0.7595[/tex]
Step-by-step explanation:
We are given that
[tex]f(x)=\frac{1}{x-1},[/tex][2,3]
We have to find L4
It means n=4
[tex]\Delta x=\frac{b-a}{n}=\frac{3-2}{4}=\frac{1}{4}=0.25[/tex]
Now, intervals are
[2,2.25],[2.25,2.50],[2.5,2.75],[2.75,3]
Now,
[tex]L_4=f(x_0)\Delta x+f(x_1)\Delta x+f(x_2)\Delta x+f(x_3)\Delta x[/tex]
[tex]L_4=\frac{1}{2-1}(0.25)+\frac{1}{2.25-1}(0.25)+\frac{1}{2.5-1}(0.25)+\frac{1}{2.75-1}(0.25)[/tex]
[tex]L_4=0.7595[/tex]
Urgent help need it plz
Answer:
angle 1 = 51
angle 2 = 34
angle 3 = 95
angle 4 = 38
angle 5 = 47
angle 6 = 74
angle 7 = 59
Step-by-step explanation:
a straight line is 180 degree, so to find angle 1, subtract 129 by 180.
angle 2 is found by adding angle 1 and 95 then subtract that by 180.
angle 3 and 95 are opposite angles, so they are the same
for angle 4, add angle three and 47 then subtract that by 180
angle 5 is 47, they are opposite
angle 7, subtract 121 by 180
angle 6, you add angle 5 and 7, and subtract that by 180
