Cosine rule: a^2<span> = b^</span>2<span> + c^</span>2<span> - 2bc </span>cos<span> A
-> a^2 > b^2 + c^2 - 2bca
-> abc > (b^2 + c^2 - a^2) /2</span>
Answer:
Choice C
Step-by-step explanation:
x^2 +6x+8
what numbers multiply together to make 8 and add together to make 6
4*2 = 8 4+2 =6
(x+2) (x+4)
Choice C
1.25 also bc they are parallel
Answer: Choice B) 5/8
================================================
Explanation:
There are 10 dots that represent a measurement larger than 1/2 a foot (either the dot is over 5/8 or 3/4 or 7/8). Call this value A, so A = 10.
There are 16 dots total. Call this B, so B = 16.
Divide A over B and then reduce: A/B = 10/16 = 5/8 so that is why the answer is choice B
Coincidentally, we end up with 5/8 but that is not the same as the "5/8" as shown on the chart. It just means that if we had 8 people, the 5 of them would have a foot size larger than half a foot.
Answer:
A = 352 in²
Step-by-step explanation:
A=2(wl+hl+hw) Use this equation to find the surface area of the rectangular prism
A = 2(8x12 + 4x12 + 4x8) Multiply
A = 2(96 + 48 + 32) Add
A = 2(176) Multiply
A = 352 in²
