Answer:

1. 15x + 3

Step-by-step explanation:

Given:

f(x) = 3x - 2

g(x) = 12x + 5

You are trying to solve:

f(x) + g(x)

Plug in the coresponding terms to the corresponding variables:

(3x - 2) + (12x + 5)

Combine like terms:

(3x + 12x) + (-2 + 5)

(15x) + (5 - 2)

15x + 3

15x + 3 is your answer.

Draw or Cut two  similar squares with sides b+c units long.


Draw or cut four  pairs of similar right triangles with side lengths as indicated in the diagram.

Now arrange the similar triangles at the corners of the squares such that the sides b of one similar triangle plus the side c  of a second similar triangle coincides with the length of the square.


We do another arrangement of the similar triangles. This time arrange another 4 similar triangles in the opposite corners, such that each pair forms a square.

Now comparing the two different arrangements we got two different areas that are equal.

The area of the uncovered squares in the first arrangement is a^2

The area of the two uncovered squares in the second arrangement is b^2+c^2

Equating the two areas gives the Pythagoras Theorem

a^2=b^2+c^2

Note that  a is the hypotenuse, b and c are two shorter sides of the similar right triangles.

Find the value of x in the triangle shown below. x = 56° 99°​
anyanavicka [17]

Answer:

x = 25 degrees

Step-by-step explanation:

All angles in a triangle should add up to 180 degrees. So to solve for x, set up an equation where all three angles added up equals 180.

180 = 99 + 56 + x

180 = 155 + x

25 = x

The unknown angle is equal to 25 degrees.

algol13

Answer:

(D) 3

Step-by-step explanation:

Prudence has 12 pairs of gold earrings and 12 pairs of silver earrings.

Total Number of Earrings =12+12=24

Relative Frequency of Picking a Gold Earrings =12/24= 0.5

If she randomly pulls six pairs of earrings out of the drawer to take with her on a trip

Number of Possible Outcome =Relative Frequency X Number of Trials

=0.5 X 6

=3

She would most likely take 3 gold earrings.
