4x+5 feet
A square has 4 sides, and all of them are the same size. Because of this, you divide the whole expression by 4, and you’re left with 4x+5.
16x/4=4x
20/4=5
2x-y=4
Therefore: y=2x-4
---------------------------------
5x-10/4(2x-4)=10
5x-5/2(2x-4)=10
5x-5x+10=10
10=10

A. Or B.
I picked this in one of my questions and I don’t remember which specific one but the one or other should be correct.
Answer:
(a)4 units, 3 units
(b) Right-angled triangle
Step-by-step explanation:
We are given that
Let location of drinking fountain, A =(-4,2)
Location of the bench, B=(0,2)
Location of the center of the slide ,C=(0,5)
a. Distance formula
Using the formula
units
Hence, the distance from the drinking fountain to the bench=4 units
The distance from the bench to the center of the slide=3 units
(b)
units
The triangle ABC satisfied the Pythagoras theorem. Hence, the triangle ABC is a right angled triangle.
Answer: The measures of the angles are 64.6 degrees and 25.4 degrees.
Step-by-step explanation:
Complementary angles add up to 90 degrees.
x can be one angle, and (x-39.2) can be the other
x + (x-39.2) = 90
2x - 39.2 = 90
add 39.2 to both sides
2x = 129.2
divide each side by 2
x = 64.6
find the measure of the other angle
64.6-39.2 = 25.4
The measures of the angles are 64.6 degrees and 25.4 degrees.
