The perimeter of an isosceles triangle is 24cm. The unequal side is twice as long as the equal sides. How long is the equal side?

Equal sides = 6cm each

Unequal side = 12cm

Step-by-step explanation:

Perimeter of a triangle = side a + side b + side c

Let

Side a = side b = x

Side c = 2x

Perimeter of the triangle=24cm

Perimeter of a triangle = side a + side b + side c

24 = x + x + 2x

24 = 4x

Divide both sides by 4

24 / 4 = 4x / 4

6 = x

x = 6

The equal sides = x = 6cm each

The unequal side = 2x

= 2(6)

= 12cm

Check:

Perimeter of a triangle = side a + side b + side c

= 6cm + 6cm + 12cm

= 24cm

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
