Question

Please help again thank you in advance

Answer 1

Answer:

20 units

Step-by-step explanation:

Since the triangle is equilateral then all 3 sides are equal in length.

Equate any 2 sides and solve for x

4x = 3x + 5 ( subtract 3x from both sides )

x = 5

hence

4x = 4 × 5 = 20

3x + 5 = (3 × 5) + 5 = 15 + 5 = 20

7x - 15 = (7 × 5) - 15 = 35 - 15 = 20

The lengths of the sides are 20 units

Answer 2

Answer:

20-20-20(20 on each side)

Step-by-step explanation:

Okay, so what it's asking is to find 'x' and plug it in to find the missing sides. But, they all are equal to one another.

So the equation could be something like this:

4x=3x+5(Just to find x)

-3x  -3x

Then you'd have x=5

You'd plug it in and you'd have your answer of 20 for each side
