−3x+9−2x=−12−5xminus

Mathematics
1 answer:
scoundrel [369]4 years ago
8 0

Answer:

x = 21/5 + m, m E R

Step-by-step explanation:

Solving Steps:

-3x=9 - 2x = -12 - 5m

collect the like terms

-5x + 9 = - 12 - 5m

move constant to the right

-5x = - 21 - 5m

Divide both sides by -5

x 21/5 + m

the final solution

x = 21/5 + m, m E R

Answer:

The point at (-7, -5) = a

The point at (9, 3) = b

The point at (-3, 7) = c

The "a" point of the triangle is 12 units away from the center point.

So, 12 x 1/4

=> 12/4

=> 3

So, the "a" point of the dilated figure is  3 units left from the center.

=> So, the dilated "a" point is at (2, -5)

The "b" point is 8/4 (= rise/run = y-axis / x-axis) from the center point.

=> 8/4 = 2

So, the "b" point of the dilated figure is 1 unit right and 2 units up from the center point.

=> So, the dilated "b" point is at (6, -3)

The "c" point is 12/8 units away from the center point.

=> 12/8 x 1/4

=> 3/2

So, the "c" point of the dilated figure is 3 units up and 2 units left from the center point.

=> So, the dilated "c" point is at (3, -2)

Which expression is equivalent to 36x² - 25?
snow_lady [41]

Answer:

\boxed{ \rm(6x)²-(5)²}

Step-by-step explanation:

Given expression/polynomial :

3 6{x}^{2}  - 25

Let's evaluate.

We can re-write the polynomial as

  • 6 {}^{2} x {}^{2}  - 5 {}^{2}

Further

  • {(6x) {}^{2} - 5 {}^{2} }

Hence, the expression is equivalent to last Choice, (6x)²-(5)².
