Answer:
(x + y)² = 35
Step-by-step explanation:
The expansion of
(x + y)² = x² + 2xy + y²
= x² + y² + 2xy ← substitute given values
= 25 + 2(5)
= 25 + 10
= 35
The answer would be 2.2.
This sentence as an expression would be n - (-3n) = n + 11.
Solve it and you'll get 2.2!
Answer:
We don't have sufficient evidence to support the claim
Step-by-step explanation:
Null hypothesis:
Alternate hypothesis:
The P-value is 0.3064
0.3064 probability of finding a sample proportion lower than the one found.
The p-value is higher than the significance level of 0.05, which means that there is no sufficient evidence to support the claim.
Answer:
Step-by-step explanation:
(-8a - 1)- (-7a + 5) = -8a - 1 - 7a*(-1) + 5*(-1) { (-1) is disturbed to all the terms in (-7a +5)}
= -8a - 1 + 7a - 5
= -8a + 7a -1 - 5 {Combine like terms}
= -a - 6
Answer:
Based off of my calculations, I got 126
Step-by-step explanation:
The formula for area would be: A = L * W
So, when finding the width (W), you would need to divide the area (A) by the length (L).
Equation: W = A / L
Now you know the equation, all you need to do is plug in the numbers:
[84 divided by 2/3]
W = 84 / 2/3
After solving this, you would get: 126
So, W = 126.
To check if we got the correct answer, we could just multiply the length times the width:
126 * 2/3
Since this equation gives us 84 as the answer, 126 is the correct width.
