Let
x-------> the length of the base of triangle
y-------> the height of the triangle
we know that
the area of the triangle is equal to
in this problem we have
so
--------> equation 
--------> equation 
Substitute equation in equation
![\frac{1}{2}x[2x+4]\leq 168](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dx%5B2x%2B4%5D%5Cleq%20168)
therefore
<u>the answer is</u>
The inequality that can be used to find the possible lengths, x, of the base of the triangle is or
The coefficient (letter chosen) that is used does not matter as it is only to show that it is an unknown variable, if you have more than one variable you need more than one type of coefficient (use different letters for different ones you dont know).
Answer:
80 ÷ 16 = 5
Step-by-step explanation:
The "family facts" seem to be related to the relationship ...
5 × 16 = 80
One of the facts is generated from this one by reversing the order of the factors:
16 × 5 = 80
The other two are found by dividing the equation by one or the other of the factors:
16 = 80/5 . . . . . divide by 5
5 = 80/16 . . . . . divide by 16
This last one is the one that is missing. It the form used in the problem statement, it is ...
80 : 16 = 5
Answer:
4
Step-by-step explanation:
Simplify the following:
2^5/2^3
Hint: | For all exponents, a^n/a^m = a^(n - m). Apply this to 2^5/2^3.
Combine powers. 2^5/2^3 = 2^(5 - 3):
2^(5 - 3)
Hint: | Subtract 3 from 5.
5 - 3 = 2:
2^2
Hint: | Evaluate 2^2.
2^2 = 4:
Answer: 4
Answer
No. The amounts of change are the same, but the original amounts are different. The ratio for the percent increase from 50 to 70 is 20/50, or 40%. The ratio for the percent decrease from 70 to 50 is 20/70, or about 29%.
