None of given </h3><h3>
x = -1²/₇ </h3>
Step-by-step explanation:
-(-10x - 8) = -(4x + 10)
10x + 8 = -4x - 10
-8 -8
10x = -4x - 18
+4x +4x
14x = -18
÷14 ÷14
x = -¹⁸/₁₄ = -⁹/₇ = -1²/₇
I think you meant -(10x-8)=-(4x+10)
Then:
-(10x - 8) = -(4x + 10)
-10x + 8 = -4x - 10
-8 -8
-10x = -4x - 18
+4x +4x
-6x = -18
÷(-6) ÷(-6)

Answer:
a² - b² = 1
Step-by-step explanation:
The given parameters are;
sec 50° = a
cot 40° = b
We note that sec(θ) = 1/cos(θ) and cot(θ) = 1/tan(θ)
a² - b² = sec²50° - cot²40°
Given that sec(90 - θ) = cosec(θ) where; cosec(θ) = 1/sin(θ), we have;
sec²50° - cot²40° = sec²(90° - 50°) - cot²40° = sec²(40°) - cot²40°
sec²(40°) - cot²40° = cosec²(40°) - cot²40°
Also we have;
cosoc²(θ) = 1 + cot²(θ)
Therefore, we have;
cosoc²(40°) - cot²40° = 1 + cot²(40°) - cot²40° = 1
Therefore, where sec(50°) = a and cot(40°) = b, the value of a² - b² is 1.
Answer:

Step-by-step explanation:
As we can see in the line plot below, we have:
2 * 1/4 = 1/2
2 * 1/2 = 1
1 * 3/4 = 3/4
Adding up, we have:
1/2 + 1 + 3/4 = 2 1/4 cups of cereal
<u>The correct answer is D. 2 1/4</u>
Answer:
10 ft by 10 ft by 10 ft works, but there are other solutions.
Step-by-step explanation:
There are many solutions.
One solution is 10 ft by 10 ft by 10 ft.
The volume then is:
10 ft * 10 ft * 10 ft = 1000 ft^3
