Triangle b because it only has 3 sides
40 ft of 60% (.6) = 24ft
Area- 24(40)=960ft
Answer:
Width: 10.5 feet
Length: 31.5 feet
Step-by-step explanation:
Let x represent width of the concrete slab.
We have been given that the length of a concrete slab is three more than three times the width. So length of the slab would be
.
We are also told that the area of slab is 330 square feet. We can represent this information in an equation as:




Now, we will take square root of both sides.


Therefore, the width of slab is approximately 10.5 feet.
The length of the slab would be
.
Therefore, the length of slab is approximately 31.5 feet.
Answer:
Step-by-step explanation:
Answer:
A, B and C (close examination)
Step-by-step explanation:
A. 15m3 - 6m = 3m(5m2 - 6m)
B. 40m6-4=4(10m6-1)
- 0 = 0
- All real numbers are solutions
C. 6m2+18m=6m2(1+3m)
D. 32m4+12m3(8m+3)
This is tough one but I will explain this problem by close examination:
The problem is looking for an equation that have the variable m by itself
D is out of the picture because the equations does not have m by itself
Equation B's answer is that all numbers are solutions meaning any m value you put will become the same. (Similar to Infinite Solutions)
By close examination, The answer are A, B, and C.
