Answer:
A. (2x-3)/2
Step-by-step explanation:
Performing the long division indicated by the perimeter expression, you find ...
perimeter = (2x -3) + (10x +6)/(x^2 +2x)
Comparing this to the formula for the perimeter ...
perimeter = 2W +2L
where L is said to be of the form (ax +b)/(x^2 +2x)
we can match terms in the perimeter expression to see that ...
2W = 2x -3
2L = (10x +6)/(x^2 +2x)
The problem doesn't ask for it, but we can see that (a, b) = (5, 3). We can also see that ...
W = (2x -3)/2 . . . . . . . matches choice A
Answer:
- 7/2
Step-by-step explanation:
- sqrt(49/4)
We know that sqrt(a/b) = sqrt(a)/ sqrt(b)
- sqrt(49)/sqrt(4)
- 7/2

Answer:
17°
Step-by-step explanation:
ΔXWZ = ΔYWZ (they are congruent triangles so ∠XWZ = ∠YWZ)
5x - 8 = 9x - 28
Rearrange and collect the like terms
-8 + 28 = 9x - 5x
20 = 4x
x = 5°
∠YWZ = 9x - 28
sub x = 5
= 45 - 28
= 17°
The slope of parallel lines is equal and the slope of perpendicular lines is a negative multiplicative inverse of each other.
<h3>What is the standard equation of a line?</h3>
The standard equation of a line is given by
y = mx+c
Here m is the slope and c is the y-intercept
The slope can be determined by
m = (y₂ -y₁)/(x₂ -x₁)
A square is a polygon with four sides, the opposite sides are parallel and all the sides are equal, all the angles have an equal measure of 90 degrees.
Two lines are parallel to each other when they are at a fixed distance always and never intersect with each other.
The slope of the lines parallel to each other is equal.
Two lines are said to be perpendicular when they intersect at 90 degrees.
The slope of two perpendicular lines has a product of -1.
