You have to look for the key words in order to find out how to solve; multiply divide etc.
Area=wide times long
area=40
4=wide
40=4 times long
divide both sides by 4
10=long
10 yd long
Answer: 2, 6
<u>Step-by-step explanation:</u>
Triangle Inequality Theorem states that the sum of two sides must be GREATER than the third side.
RS + ST > RT and RS + RT > ST and ST + RT > RS
2x + 4x > 12 2x + 12 > 4x 4x + 12 > 2x
6x > 12 12 > 2x 12 > -2x
x > 2 6 > x -6 < x
2 < x x < 6 invalid
Answer: 2 < x < 6
Graph: O----------------------O
2 6
<em> Note: -6 is invalid because you cannot have a negative length. </em>
I just had this question for homework too!
c = 4v + 1
v + c = 121
Now use substitution.
v + 4v + 1 = 121
5v + 1 = 121
5v = 120
v = 24
The answer is 24.
