He made an error in step 1. Specifically, he distributed incorrectly.
The 3(x+2) portion is not the same as 3x+2. We need to multiply that '3' by the 2 as well to get 3*2 = 6
In other words, 3(x+2) should turn into 3x+6
If you wanted, you can think of 3(x+2) as three copies of (x+2) added together like this: (x+2)+(x+2)+(x+2) = (x+x+x)+(2+2+2) = 3x+6

Xavier surveyed a random sample of the grade levels of the Spanish Club members in the county. The bar graph shows the results of his survey.
The bar graph is titled Random Sample of Spanish Club Members. The horizontal axis is labeled Grade level and lists four grades: ninth to twelfth. The vertical axis is labeled Number of members from zero to fourteen by twos. Ninth, eight. Tenth, fourteen. Eleventh, five. Twelfth, three.
Of the 300 students in the Spanish Club in the county, predict how many are 9th graders
Answer:
80
Step-by-step explanation:
If you add each value it equals 30.
30x10=300 so 8 (value of the 9th grade bar) times 10 equals 80.

A triangular prism. The rectangular sides are 12 feet by 3 feet, 12 feet by 5 feet, and 12 feet by 4 feet. The 2 triangular sides have a base of 3 feet and height of 4 feet.
The area of each triangular base is:
A = 1/2(b)(h)
A = 1/2(3)(4)
A =
ft2
There are two bases, so total base area is
ft2.
The lateral area is:
A = (12)(3) + 12(5) + 12(4)
A =
ft2
The total surface area is
ft2.

write and solve a real world problem that can be solved using the greatest common factor of two numbers
Answer:
Wendy is filling in party goodie bags with toy cars and helicopters. There are 56 toy cars and 77 helicopters. Each bag must only have either toy car or helicopter - there is no mixing of toys.
Each bag must have the same number of toy cars in it.
Each bag must have the same number of toy helicopter in it.
All bags must have the same number of toys in it.
a) How many bags will contain toy cars?
b) How many bags will contain toy helicopters?
-------------------------------------------------------------------------------------------------------------
Answer:
Think of highest common factor of 56 and 77
Both numbers are divisible by 1, 2, and 7 and the highest common factor is 7
56 ÷ 7 = 8
77 ÷ 7 = 11
There are 8 bags that contain equal numbers of toy cars and 11 bags that contain equal number of helicopter toy

Solve the system of linear equations by elimination.
2x+5y=16
3x−5y=−1
Get (x,y)
Answer:
(3,2)
Step-by-step explanation:
2x+5y=16
3x-5y=-1
Subtract 2x from the first equation
5y=16-2x
Substitute the given value of 5y into the equation
3x-(5y)=16
3x-(16-2x)=-1
Solve for x
3x-(16-2x)=-1
3x-16+2x=-1
5x-16=-1
5x=15
x=3
Substitute the given value of x into the equation
3x-5y=-1
3*3-5y=-1
Solve
3*3-5y=-1
9-5y=-1
-5y=-10
y=2
