Answer:
8x - 11
Step-by-step explanation:
?
just do the multiplications and add things up.
1 + 4(2x - 3) = 1 + 8x -12 = 8x - 11
The surface area of the figure is the amount of area covered by the figure.
The figure is not given, so I will give a general solution.
The method followed by Brad to calculate the surface area of the prism is correct.
However, whether Brad correctly calculates the areas of the rectangular prism and the triangular prism cannot be determined.
So, the conclusion is that:
- If Brad's calculation of the surface areas of the prisms is correct, then the surface area of the figure is correct because 1104 + 1008 = 2112.
- If otherwise, then the solution is incorrect

Adjacent means angles are near together & make 180° angel
Solve the inequality just like you would solve an equation
<span>3x - 12 > 15
add 12 to both sides
3x > 27
divide both sides by 3
x > 9
Or read as "the solution to </span><span>3x - 12 > 15 is x is greater than 9"
Hope this helps :)</span>
Answer:
The meal must cost less than or equal to 19.92
Step-by-step explanation:
Let x be the cost of the mean
First find the tax
tax = x* 5.5%
=.055x
Then find the tip
tip = x * 20%
tip = .20x
Add the total cost together
total cost = meal + tax + tip
=x + .055x + .20x
=1.255x
This must be less than or equal to 25
1.255x ≤ 25
Divide each side by 1.255
1.255x/1.255 ≤ 25/1.255
x ≤ 19.92
