The formula for surface area of a triangular prism is
SA = 2(L)(W) + 2(W)(H) + 2(H)(L) * 1/2
SA = 2(3)(2) + 2(2)(4) + 2(4)(3) * 1/2
SA = 12 + 16 + 24 * 1/2
SA = 52 *1/2
SA= 26sq in
I hope this helped!:)
Answer:
(a) -5 + (-3)
(b) -5 + 3
Step-by-step explanation:
#1 4/8 + 5/8 + 6/8 = 15/8 = 1 7/8
The correct answer is 1 7/8.
#2 The correct answer is YES.
Answer:
y = 7/5x + 4
Step-by-step explanation:
use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.
(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4
15 x 45 = 675
45 x 135 =6075
