The perimeter of the triangle is 13 inches. What is the length of the shortest side?

netineya [11]

Answer:

shortest side = 3 in

Step-by-step explanation:

Sum the 3 sides and equate to 13, that is

x - 5 + 6 + $\frac{x}{2}$ = 13, that is

x + 1 + $\frac{x}{2}$ = 13 ( subtract 1 from both sides )

x + $\frac{x}{2}$ = 12 ( multiply through by 2 to clear the fraction )

2x + x = 24

3x = 24 ( divide both sides by 3 )

x = 8

Thus

x - 5 = 8 - 5 = 3 and $\frac{x}{2}$ = $\frac{8}{2}$ = 4 , then

The shortest side is x - 5 = 3 in

$\frac{x {}^{3} - 3x {}^{2} - 10x {}^{2} + 30x + 4x - 12 }{x - 3 } \\ \frac{x {}^{2} \times (x - 3) - 10x \times (x - 3) + 4 \times (x - 3) }{x - 3} \\ \frac{(x - 3)(x {}^{2} - 10x + 4 )}{x - 3} \\ x {}^{2} - 10x + 4$

Kevin works 3z hours each day from Monday to Friday. He works (4z-7) on Saturday. Kevin does not work on Sunday. Find the number

marta [7]

During a week:
Kevin works 3z during 5 days
kevin work (4z-7) during 1 day.
Kevin work 0 during 1 day.

z=unit time
f(z)= number of hours kevin works in one week.

f(z)=5(3z)+(4z-7)+0
f(z)=15z+4z-7
f(z)=19z-7

The number of hours kevin woirs in one week in terms of z is:
f(z)=19z-7
