Answer:
7 in
Step-by-step explanation:
perimeter = 2length + 2width
Input the given info:
24 = 2length + 2(5)
24 = 2L + 10
14 = 2L
14/2 = L
l = 7

Some things you need to know:
1) You need to know how to convert standard form to slope y-int. form and slope y-int. form to standard form.
2) When two lines are parallel, the slopes are the same.
3) When two lines are perpendicular, the slopes are negative reciprocals of each other. (Or their product is -1)
example: 3/4 --> -4/3.
3/4 * -4/3 = -12/12 = -1
4) To find the value of b, substitute the point into the equation.
5) Convert the equation to slope y-int. form to find the slope.
6) When a line has an undefined slope, the slope y-int. will look either like
y = __ (forms horizontal line) or x = __ (forms vertical line).
To find the perpendicular of these lines, turn y to x / x to y.
To find the value of __, look at the point located in the line, so if x = ___
passes through (5,3), then x = 5 because x = 5 in the point. So the
equation would be x = 5.
Use online practice tests and other sources if you don't understand.
4x = 3/8
there are 2 ways to do this...
(1) 4x = 3/8....divide both sides by 4
x = (3/8) / 4
x = 3/8 * 1/4
x = 3/32 <==
or
(2) 4x = 3/8....multiply both sides by 1/4, cancelling out the 4 on the left
x = 3/8 * 1/4
x = 3/32 <==
Answer:
C
Step-by-step explanation:
The triangle inequality theorem tells us that if two sides of a triangle are known (let it be side a and b), we can know the length of range of third side (side c). By:
a-b< c < a+b
So sides are given 29 and 40.
Sum is 29 + 40 = 69
Difference is 40 - 29 = 11
Hence, the third side would be BETWEEN 11 and 69
C is the correct choice.
