Okay! So to start this problem, we need to look at the given information a little closer to make sure we have everything we need! This is a triangular pyramid, meaning that it has a total of 4 sides, which are all congruent triangles, meaning they all have the same surface area! We are also given the total surface area, which is 2304 cm^2.
If we need to find out how big one of the sides are, we should just have to divide the total surface area by 4, because there are 4 sides with the same surface area! 2304/4 = 576 cm^2, so your answer should be A) 576 cm2!

yeppp that's itttt
Answer:
length = 12 feet and width = 8 feet
Step-by-step explanation:
since the area = 96 ft² then
(x + 1)(x - 3) = 96 ( A = lw )
expand the factors on the left side
x² - 2x - 3 = 96 ( subtract 96 from both sides )
x² - 2x - 99 = 0 ← in standard form
(x - 11)(x + 9) = 0 ← in factored form
equate each factor to zero and solve for x
x - 11 = 0 ⇒ x = 11
x + 9 = 0 ⇒ x = - 9
but x > 0 ⇒ x = 11
length = 11 + 1 = 12 feet and width = 11 - 3 = 8 feet
Answer:
f=8
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
DE / XY = EF / YZ
5 / 10 = 2x-1 / 14
cross-multiply:
10(2x-1) = 14(5)
20x - 10 = 70
20x = 80
x = 4
