Answer:

b.) All real numbers.

Step-by-step explanation:

4 (a + 3) = 12 + 4a

4a + 12 = 12 + 4a

4a + 12 - 12 = 12 + 4a - 12

4a = 4a

4a/4 = 4a/4

0 = 0

All possibilities of other real 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 rectangle has an area of 96 cm2 The length of the rectangle is 4 cm longer than the width. Work out the length and width of th

Svetach [21]

Area of a rectangle: 2(L+W)
length: 4+W

Area: 2(4+W) + 2W = 96
8+2W+2W = 96
8+4W = 96
4W = 88
W= 22cm

Calculate for length: 2L + 2(22) = 96
2L + 44 = 96
2L = 52
L = 26cm

• The length is 26cm and width is 22 cm.
