Answer:

x = $y^{2}$ - 4y + 12

Step-by-step explanation:

y = 2 + $\sqrt{x-8}$

Put the 2 on the other side

y - 2 = $\sqrt{x-8}$

Square both sides

$(y-2)^{2}$ = x - 8

Expand the brackets

$y^{2}$ - 4y + 4 = x-8

Move 8 to the other side

x = $y^{2}$ - 4y + 12

Maristella is constructing an isosceles triangle to use as a model in her Algebra class. The perimeter of her triangle is 24 cm.

Vlada [557]

Isolating s, the equation written in terms of s is:

$s = 12 - 0.5b$

-------------------------

The equation for the length of the third side, as stated in the problem,("Maristella uses the equation b = 24 – 2s to find b, the length of the triangle's third side") is:

$b = 24 - 2s$

To solve for the lengths of the congruent sides, we isolate s, thus:

$b = 24 - 2s$

$2s = 24 - b$

Inverse of multiplication is division, thus:

$s = \frac{24 - b}{2}$

Separating into two fractions:

$s = \frac{24}{2} - \frac{b}{2}$

Solving each fraction:

$s = 12 - 0.5b$
