Answer:

b.) All real numbers.

Step-by-step explanation:

4 (<em>a </em>+ 3) = 12 + 4<em>a </em>

4<em>a</em> + 12 = 12 + 4<em>a </em>

4<em>a </em>+ 12 - 12 = 12 + 4<em>a </em>- 12

4<em>a </em>= 4<em>a </em>

4<em>a</em>/4 = 4<em>a</em>/4

0 = 0

All possibilities of other <em>real </em>number can fit into the equation. Hence, the answer is b.) All real numbers.

4(a + 3) = 12 + 4a
4a + 12 = 12 + 4a
0 = 0

Therefore, the solution to the equation is all real numbers.

A rectangular picture frame measures 63 cm by 63 cm. What is the perimeter or distance around the picture frame in meters? m
Natalija [7]
Hi!

We need the perimeter in meters, so we have to turn cm into m. 
63 cm = 0.63 m

The perimeter is the sum of all side measures:
P = 0.63 + 0.63 + 0.63 + 0.63
P = 4 * 0.63
P = 2.52 m

Answer: x = 11

Step-by-step explanation:

same as the last question, set them as equal and solve. here's my work:

<em>5x - 1 = 4x + 10</em>

<em>5x - 1 (+ 1) = 4x + 10 (+ 1)</em>

<em>5x = 4x + 11</em>

<em>5x (- 4x) = 4x (- 4x) + 11</em>

x = 11
