if ab=12 and a^2+b^2=25 ,then what is (a+b)^2=​

Answers

Answer 1
Answer:

I think it’s a^2+2ab+b^2
Answer 2

Answer:

49

Step-by-step explanation:

Multiply out (a+b)^2

(a+b)^2 = (a+b)(a+b) = a^2 + ab + ba + b^2 ; not ab = ba so,

= a^2 + 2ab + b^2 = a^2 + b^2 + 2ab ; now subtitue in given values

=25 + 2(12) = 25 + 24 = 49

So (a+b)^2 = 49

If the scale factor of volumes of 2 similar shapes is 15.625

If the scale factor is one, it means that corresponding sides are equal in length. In this case the shapes would be congruent (ie identical) rather than similar. They have the same shape, the same angles and the same size.

Solve the Quadratic equation
8n²-56=48n

Answers

Answer:

n = {-1, 7}

Step-by-step explanation:

8n² - 56 = 48n

Subtract 48n from both sides

8n² - 48n - 56 = 0

Divide both sides by 8

n² - 6n - 7 = 0

Factor

alternately use the quadratic equation or complete the square

(n - 7)(n + 1) = 0

n = {-1, 7}

the x-intercept of the graph of f(x)=3log(x-5)+2 is:

Answers

Answer:

C

Step-by-step explanation:

To find the x- intercept let f(x) = 0 , then

3log(x - 5) + 2 = 0 ( subtract 2 from both sides )

3log(x - 5) = - 2 ( divide both sides by 3 )

log(x - 5) = - [tex]\frac{2}{3}[/tex] , then

x - 5 = [tex]10^{-\frac{2}{3} }[/tex] ( add 5 to both sides )

x = [tex]10^{-\frac{2}{3} }[/tex] + 5 → C

X coordinates come first, and A is in between -2 and -3 at -2.5, and B is between 4 and 5 so we have 4.5

Then we have y coordinates, and A is between -1 and -2 so -1.5, and B is between -3 and -4, so -3.5.

I know how to apply the midpoint theorem, but I don't know where I should start my intervals.

Answers

We have that for the Question "I know how to apply the midpoint theorem, but I don't know where I should start my intervals." it can be said that

Where you start your intervals are at the (x,y) co-ordinate of the Reference points

From the question we are told

I know how to apply the midpoint theorem, but I don't know where I should start my intervals.

Generally the equation for the midpoint   is mathematically given as

[tex]m=\frac{x1+x2}{2},\frac{y1+y2}{2}[/tex]

Naturally the midpoint of two point is the point in between the reference points where distances from them are equal

Therefore

Midpoints co-ordinates simply considers the co-ordinate of the two main reference points.(x,y)

Hence

Where you start your intervals are at the (x,y) co-ordinate of the Reference points
