Answer:
Area = 18 ft³ Surface Area = 44 ft²
Step-by-step explanation:
The formula for the area of a rectangular prism is A=lwh so you just plug in the numbers. For surface area, you have to find the area for each face and add them together.
They are all integers so...
first lets substitute
A.3x=13
X=13/3
b.3x+2=13
3x=11
x=11/3
c.3x+4=13
3x=9
x=3
d.3x+6=13
3x=7
x=7/3
E.3x+8=13
3x=5
x=5/3
therefore the possible is letter c because it must be an integer and the definition of integer states that it is not a decimal nor a fraction
Answer:
4
Step-by-step explanation:
Answer:
x = 9
Step-by-step explanation:
23 - 5 = 18
18 ÷ 2 = 9......
Lets plug in the numbers
2 times 2-3
4-3
1
your answer is 1
