Question

Dwayne's garden is triangle-shaped with two equal sides and a third side that is 4 ft more than the length of an equal side. If the perimeter is 49 ft, how long is each side?

Which equation represents this?


2x = 49
2x + 4 = 49
3x = 49
3x + 4 = 49

Answer 1

the answer is d

Explanation:

Answer 2

The perimeter of a figure is the sum of the measures of all its sides. Let x be the measure of the two equal side. Then, the third side becomes x+4. The equation that represents this is,
x + x + (x + 4) = 49
Simplifying this would give an answer of,
3x + 4 = 49
This is the fourth choice of letter D.
