If you look at the rectangle properly, you can see that the diagonal creates two triangles, and if we only focus on one triangle, we can see that the bad of the triangle is 7 and the perpendicular height is 4
Using Pythagorean theorem we can figure out the hypotenuse, or the diagonal
C squared is equal to a squared plus b squared
7^2+4^2 is 65

Answer:
y= 5 and -3
Step-by-step explanation:
subtract 7 from both sides to get y^2-2y-15=0
factor the equation to get (y-5)(y+3)=0
add five on both sides to get y=5 and subtract 3 on both sides to get y=-3
Answer: Circumference of circle = 27.004 inches
Area of circle = 58.0586 inches²
Step-by-step explanation:
Diameter of circle = 8.6 inches
Pi (
) = 3.14
Circumference of circle (With diameter) = 
d (×diameter)
= 3.14 × 8.6
= 27.004 inches
Area of circle (With diameter) = 
/4
= 3.14 × 8.6 × 8.6 / 4
= 3.14 × 73.96 / 4
= 58.0586 inches²
