The answer would be A.-(+8 1/4)
The answer is B. 3a = 12.
3 times A with A being 4 equals 12.
Answer: (A) 2(x + 4)
Step-by-step explanation: We know that the measure of one side of the square is (x + 4). But, we first will need to find the total area and perimeter of the square in order to find the difference between them.
The area is length x width, so multiply 2(x + 4) Since all the sides are the same.
2(x + 4) = 2x + 8. The area is 2x + 8.
To find the perimeter simply add x + 4, four times. 4(x + 4).
4(x + 4) = 4x + 16 as the total perimeter of the square.
Now subtract the area from the perimeter.
4x + 16 - (2x + 8) --Distribute negative sign.
4x + 16 - 2x - 8 --Combine like terms
4x - 2x + 16 - 8
2x + 8.
2(x + 4) is equivalent to 2x + 8 and is therefore the answer.
Answer:
y = - 6x - 2
Step-by-step explanation:
The straight line equation is y = mx + c
First step is to bring the equation given to this form, where you make y the subject.
Now you can easily note down the gradient(m1). You will need it to find the gradient(m2) of the perpendicular line, because m1 × m2 = -1
After you have that substitute the value and the values of x and y given to find c .
Lastly, substitute the value of m2 and c into y = mx + c to find the line that is perpendicular .
Hope I was able to help:)))
Answer:
After calculating values from test statics we come to know that value of if null hypothesis is true then it will rejected
As critical values of z is ±1.96 after apply the test statics formula , we get the value of z that is - 4.50 As we consider the equation that
H₀ > z
Apply test statistic we fine the true value . So there is sufficient evidence to reject the claim.
Step-by-step explanation:
critical values z₀ = ±1.96; standardized test statistic z ≅ -4.50;
reject H₀
There is sufficient evidence to reject the claim.
