Answer:

heres what you need to do

Step-by-step explanation:

1.(-7a'y+xy+3x+2)+(5r^{2}y-5cy-6x-7)\\

combine like terms

(-7a*2y+4x+2)=(5r^{2}*2y-5c-7)

now combine from both sides

(-7a*4y-2x+5r^2-5)

this is what i got srry in advanced if i was wrong

A clock has a diameter of 16 inches. Which measurement is closest to the area of the clock in square inches? 804.25 in2 50.27 in
meriva

Answer:

200.96 in2

Step-by-step explanation:

Area of a circle = nr²

n = 3.14

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

diameter = 2r

radius = 16 inches / 2 = 8 in

Area = 3.14 x 8² =  200.96 in²
