Answer:

Equivalent to a), b), and d). It is NOT equivalent to c).

Step-by-step explanation:

6m + 12 is also equivalent to a) 3(2m+4) because when you distribute, it's 6m + 12. It is also equivalent to b) 3m + 8 + 4 + 3m because if you add them together, you get 6m + 12. It is not equivalent to c) but is do d) 4m + 2(m + 6) cause you use the distributive property then add. I hope this helped and please mark brainliest!

By geometry, there is a relationship between the tangent PA and the segments PB and PE, namely
PA^2=PB*PE
so
PE=PA^2/PA=6^2/4=9
BE=PB-PE=9-4=5

random sample has been taken from a normal population and two confidence intervals constructed using exactly the same data. The

Zepler [3.9K]

The sample mean of the random sample is 50

The margin of error (E) is the amount of error allowed in the random sample.

The confidence interval (CI) is given by:

CI = μ ± E = (μ - E, μ + E)

Given a confidence interval of (38.02, 61.98), hence:

μ - E = 38.02 (1)

μ + E = 61.98 (2)

Hence solving equations 1 and 2 simultaneously gives:

μ = 50, E = 11.98

Hence the sample mean of the random sample is 50

Mr. Walker gave his class the function f(x) = (x + 3)(x + 5). Four students made a claim about the function. Each student’s clai

stich3 [128]

Answer:

Stephen's claim is correct.

Step-by-step explanation:

The given function is

$f(x)=(x+3)(x+5)$

Put x=0 to find the y-intercepts.

$f(0)=(0+3)(0+5)=3\times 5=15$

The y-intercept of the function is at (0,15). It means jeremiah's statement is incorrect.

Put f(x)=0, to find the x-intercept.

$0=(x+3)(x+5)$

$x+3=0\Rightarrow x=-3$

$x+5=0\Rightarrow x=-5$

The x-intercepts are at (-3,0) and (-5,0). It means Lindsay's statement is incorrect.

$f(x)=(x+3)(x+5)$

$f(x)=x^2+8x+15$

$f(x)=x^2+8x+15+16-16$

$f(x)=(x^2+8x+16)-1$

$f(x)=(x+4)^2-1$ .... (1)

The vertex form of a parabola is

$f(x)=(x-h)^2+k$ .... (2)

Where, (h,k) is vertex.

From (1) and (2) it is clear that the vertex of the parabola is (-4,-1), Stephen's claim is correct.

The midpoint between the x-intercepts is

$(\frac{-3-5}{2},\frac{0+0}{2})=(-4,0)$

The midpoint between the x-intercepts is at (-4, 0). It means Alexis's statement is incorrect.
