Answer: A=448+196pi, P=60+14pi
Step-by-step explanation:
I'm assuming that the figures which appear to be semicircles are semicircles and that the quadrilateral is a rectangle.
The perimeter is 16 + 16 + 28 + (28/2)(pi)= 60+14pi
area is area of rectangle + area of semicircle
= (16)(28)+(pi)(14)(14)=448+196pi
Frank can do 150 push-ups in 2 minutes
explanation: 40 x 3 = 120 = 2 minutes
50 x 3 = 150 = 150 push-ups
Answer:
y^2 +2x^2 y
----------------------
5 xy^2 - 6 x^2
Step-by-step explanation:
1/x^2 +2/y
-------------------
5/x - 6/y^2
Multiply the top and bottom by x^2y^2 to clear the fractions in the numerator and denominator
1/x^2 +2/y x^2y^2
------------------- * ---------------------------
5/x - 6/y^2 x^2y^2
Distribute
1/x^2 * x^2y^2 +2/y *x^2y^2
---------------------------------------------
5/x * x^2y^2 - 6/y^2* x^2y^2
y^2 +2x^2 y
----------------------
5 xy^2 - 6 x^2
