Answer:
B. (1/2)(4)(11)
Step-by-step explanation:
The length of the base is the sum of the lengths that make it up:
3 + 8 = 11 . . . . feet
The height is 4 ft, so the area is ...
A = 1/2bh
A = 1/2(11)(4) . . . . . equivalent to choice B
To solve this problem, we can set two equations.
Let x be the cost of coffee and y be the cost of latte.
Two coffees and one latte: 2x + y = 10.50
y=10.50 - 2x ...(1)
Three coffees and two lattes: 3x + 2y = 17.00...(2)
Put (1) into (2), we have:
3x + 2(10.50-2x) = 17.00
3x + 2(10.50) - 2(2x) = 17.00
3x + 21 - 4x = 17
Put the unknown to one side:
3x -4x = 17 - 21
-x = -4
When there are negative numbers on both sides, we can take the negative signs away:
x= 4
Therefore, cost of one coffee is A. $4.00.

Answer:
Option 3 - The value of c is 3.
Step-by-step explanation:
Given : If 32 Superscript 2 c Baseline = 8 Superscript c + 7.
To find : What is the value of c?
Solution :
Superscript denotes the power.
32 Superscript 2 c i.e. 
8 Superscript c + 7 i.e. 
The equation form is 
.
Write the expression as,
Comparing the base,
Therefore, the value of c is 3.
So option 3 is correct.
