Answer:
The value of x is 6
Step-by-step explanation:
The perimeter of an equilateral triangle is P = 3 × S, where S is the length of each side
∵ The perimeter of an equilateral triangle is 63 inches
∴ P = 63 inches
→ By using the rule of the perimeter above
∵ P = 3 × S
→ Equate the right sides of P
∴ 3 × S = 63
→ Divide both sides by 3
∴ S = 21 inches
∴ The length of each side is 21 inches
∵ The length of each side is (4x - 3)
→ Equate (4x - 3) by the length of each side
∴ 4x - 3 = 21
→ Add 3 to both sides
∵ 4x - 3 + 3 = 21 + 3
∴ 4x = 24
→ Divide both sides by 4 to find x
∴ x = 6
∴ The value of x is 6
Answer:
the answer has to be 3(17-y)
Step-by-step explanation:
I'm pretty sure about that cause what I did at first is subtract the numbers.
<em>6</em><em>0</em><em>-3y-9</em>
=51-3y
factor our 3 from the expression.
3(17-y)
