Perimeter is basicly adding all the side of the shape together.
A square have the same amount of length in every side.
So: 16+16+16+16=64
~Jz
38 + p
He scored 58 points total if she scored 20 in the second half
Adding up the number of the points earned in the first half (38) and the number of points earned in the second half (p) will give you the total points.
If he scored 20 points in the second half of the game, then you can change the expression to:
38 + 20
Because now you know what he scored in both the first half and the second half. Then you can add them together to get the answer of 58
I'm guessing x means the hypotenuse
Use Pythagoras
a^2 + b^2 = c^2
8^ + 15^2 =c^2
64 + 225 = c^2
289 = c^2
c = 17
x = 17
Answer:
Step-by-step explanation:(a)
1.65p+1.36j=118.17 and p+j=79
We can say p=79-j and sub this value in first equation
1.65(79-j)+1.36j=118.17
130.35-1.65j+1.36j=118.17
-0.29=-12.18
j=42, p=79-j, p=79-42=37
(b)
1.65(37)=61.05 and 1.36(42)=57.12
Sanchez class earned more selling pies.
(c)
61.05-57.12=3.93
So Sanchez class made $3.93 more than Kelley class.
