For Right angled triangle area
A=ab/2
(2x-2)(4x+2)/2
(8x^2+4x-8x-4)/2
(8x^2-4x-4)/2 take common term 2
2(4x^2-2x-2)/2
So A=4x^2-2x-2
Answer:
0.88%y + 0.03%
Step-by-step explanation:
if it's 12% then: she's actually paid 88% with a tax of 3%.
The answer is a prism. If you think about it when you cut a cone, cylinder, or sphere in half you get a circle. If you cut a prism you'd get a quadrilateral.
Answer:
To find the volume you will find each volume separately. The volumes will be found by finding the areas of the bases and multiplying them by the heights.
V = BH
23.4 x 3 = 70.2 cubic inches for The hexagonal prism and. 9 x 3 = 27 cubic inches for the cube
97.2 cubic inches is the total volume.
FIRST ONE
Answer:
x=17/5
Step-by-step explanation:
2 1/5=11/5
5 3/5=28/5
------------------
x+11/5=28/5
x=28/5-11/5
x=17/5
