Evaluate the expression for x2 +y2 for x =-5 and y = -2​

If that’s supposed to be x squared and y squared then it would be: -5^2 + -2^2=29

If it’s x and y multiplied by 2 then the answer would be (-5 x 2) + (-2 x 2) = -14.

Answer:

358 yds

Step-by-step explanation:

To find the area of a rectangle it is length * height

Top rectangle= 12 * 6= 72

Middles rectangle= 27 * 8= 216

For the trapezoid you can use this formula A = (a + b) * h / 2

A = (11 + 9) * 7 divided by 2

Area of the trapezoid is 70

Then add ALL the shape areas together

72 + 216 + 70= 358

PLZ EXPLAIN , I WANT TO KNOW HOW TO DO
Phantasy [73]
Make sure you know the formula pertaining to the question. 

1. c=2(pi)(r)
2. c=2(pi)(d)

r= radius 
d= diameter
c= sircumference

So we are given that the circumference of a circle is 12.3pi and the radius is unknown. 

So let's plug in the known values 

**we use the formula with the radius, becuase we are looking for the radius. 

c=2(pi)(r)
12.3(pi)=2(pi)(r)

divide each side by pi

12.3=2(r)

divide each side by 2

r=6.15 in.
