The length of the sides of a triangle are in the ratio 3:5:7. The difference between the longest side and the shortest side is 2
4cm. What is the perimeter of the triangle?
1 answer:
Answer:
P = 90 cm
Step-by-step explanation:
Let the sides of a triangle are 3x,5x and 7x.
The difference between the longest side and the shortest side is 24cm i.e.
7x-3x = 24
4x = 24
x = 6
Sides are :
3x = 3(6) = 18 cm
5x = 5(6) = 30 cm
7x = 7(6) = 42 cm
Perimeter = sum of all sides
P = 18+30+42
P= 90 cm
Hence, the perimeter of the triangle is equal to 90 cm.

Answer:
x = 3.8
Step-by-step explanation:
The equation is (5 - x) / 2 = 2x - 7
Multiply both sides by 2:
5 - x = 4x - 14
Add 14 to both sides:
19 - x = 4x
Add x to both sides:
19 = 5x
Divide both sides by 5 to isolate x:
3.8 = x
Therefore, x = 3.8.
A, dilation because the shape got larger. The other three options just move it around
the fraction 8/1 because when dividing fractions you want to flip the second fraction aka 8/1 and multiply the two together.
ex:
3 ÷ 8/1
3/1 × 1/8
answer- 3/24

Answer:
the 3rd
Step-by-step explanation:
because n^2+3n+2n simplifies to n(n+5), which is not equivalent to 6n
