First we find the area of the two triangles on each side (keep in mind that they are equal/congruent to each other):
(24*10)/2 = 120 cm^2
Then you find the areas of the three rectangles that are left:
24*19 = 456 cm^2
26*19 = 494 cm^2
10*19 = 190 cm^2
Finally, to find the surface area of the prism:
120+120+456+494+190 = 1,380 cm^2
Answer:
(8x-5y)(8x+5y)
Step-by-step explanation:
Using the square principal because the square root of 64x2 is 8x and the square root of 25y2 is 5y and +- because +times- is only minus and the equation is minus.
D. (I used 3.14 as pi so my answer was a little off so I just went with the one closest to my answer)
-3(4x-8.2) < -11.98x + 14 3/4
Expand by using distributive property
-12x + 24.6 < -11.98x + 14.75
Subtract 24.6 from both sides
-12x < -11.98x - 9.85
Add both sides by -11.98x
-0.02x < - 9.85
Divide both sides by -0.02 (sign will be flipped)
x > 492.5
