3(c-4)=4(c-6)<br> i don't know how to solve it, either

STatiana [176]

Answer:

c = 12

Step-by-step explanation:

3(c - 4) = 4(c - 6)

Use the distributive property on each side.

3c - 12 = 4c - 24

Now you need the terms with c on the left side and the numbers on the right side. Subtract 4c from both sides. Add 12 to both sides.

3c - 4c - 12 + 12 = 4c - 4c - 24 + 12

Combine like terms on each side.

-c = -12

Multiply both sides by -1.

c = 12

The perimeter of a triangle is 16x−6. If two sides measure 3x+2 and 4x−9, then how long is the third side?

Studentka2010 [4]

Perimeter of a triangle is the sum of measures of its all three sides, let the other be y,

we know,

$\hookrightarrow \: y + 3x + 2 + 4x - 9 = 16x - 6$

$\hookrightarrow \: y + 7x - 7 = 16x - 6$

$\hookrightarrow \: y = 16x - 6 - 7x + 7$

$\hookrightarrow \: y = 6x + 1$

hence, measure of the third side is 6x + 1
