Answer:
400 sq. ft.
Step-by-step explanation:
We gotta find the length of a side:
First, we divide 80 by 4, because the perimeter of a square is (4 x side):
80 ft. / 4 = 20 ft.
Second, we doing the normal area of a square equation:
= 400 square ft.
Which leads to out answer of 400 sq. ft.
1h 35min + 1h 35min = 3h 10min
Answer:
First one - the root is in the bottom of the fraction (just like it is with trees) and she wrote it backwards. 2 to the four over three is the third root of two the power of four and not the other way around. Just change that and it's good.
Second one - he said that ln(2) = 2 and that's just not true. No way of fixing that one, he shouldn't get high as often as he does I guess.
Step-by-step explanation:
| -6x - 3 | > 15
This expression can be written as:
a) -6x - 3 > 15
b) -15 > - 6x - 3
Solving a part:
Solving b part:
or we can write:
x > 2
So the solution to given inequality is:
The second option correctly lists this solution.
Answer: C. 4.86
Step-by-step explanation:
Given : The two rectangles below have the same height-to-width ratio.
Since , width of blue rectangle = 34 units
Height of blue rectangle = 21 units
and width of red rectangle = w units
Height of red rectangle = 3 units
Then, 
i.e. 
Hence, The value of w= 4.86
