Answer:

7(3 + 3x) = 21x + 21

2d + 10(4d +4 + 2a) = 20a + 42d + 40

3t + 2x + x = 3t + 3x

5(r + 12) - 25 = 5r + 35

18s + 12rs + 10r - 2rs = 10rs + 10r + 18s

s(12 - 4) + 2 = 8s + 2

w(15 - 3) + 2 + 7w = 19w + 2

Step-by-step explanation:

HURRY PLEASE I WILL GIVE BRAINLIEST AND LOTS OF POINTS

Mrac [35]

Answer:

$m = \dfrac{3}{4}$

Step-by-step explanation:

We would like to find the slope of the line of the given equation .

$\longrightarrow y =\dfrac{3}{4}x -1$

We know that slope intercept form of the line is given by ,

$\longrightarrow y = mx + c$

where ,

m is the slope
c is y intercept

Now we can compare the given equation with the slope intercept form to find the slope . You will see that 3/4 is present at the place of m .Therefore ,

$\longrightarrow \underline{\underline{m=\dfrac{3}{4}}}$

Hence option C is correct choice .

What else would need to be congruent to show that ABC =XYZ by SAS? Given: AB=XY A=X

Sati [7]

ABC = XYZ by SAS

AB = XY - Side

A = X - Angle

So you want to find another congruent side.

Removing the taken possible side, two sides can be congruent.

Either :

BC = YZ

OR

AC = XZ
