Answer:
The length of each of the 4 sides of a square is the same. Then
5x - 8 = 3x
2x = 8
x = 4
5(4) - 8 = 12
3(4) = 12
The length of each side is
L = 4.
The perimeter is 4 times the length.
P = 4L = 4(4) = 16
Step-by-step explanation:
This is a ratio problem. First, we need to add the number of students polled.
7 + 4 + 3 + 6 = 20
Next, look at how many out of 20 students selected Science.
3 out of 20.
Say it this way:
3 is to 20 as ? is to 400.
Express it this way:
3/20 = x/400
Cross multiply to eliminate the denominators.
3 x 400 = 20 x Now solve for x.
1200 = 20 x
x = 60
Check it!
Does 60/400 reduce to 3/20? Yes!
60 students are predicted to select science out of 400

Answer:
HL
Step-by-step explanation:
You have a the two hypotenuses from the two triangles are congruent.
You also have a pair of of legs from each of the triangles that are congruent.
So HL means hypotenuse-leg which is what you have in the pic!
