Consider triangle ABC where AB=X+5, BC=X-2, area is 30cm squared. Find X by solving X^2+3X-70=0, and find the perimeter.

klasskru [66]

Answer:

What the hell AC is not given so you can't find the Perimeter

Step-by-step explanation:

x^2+3x-70=0

(x-7)(x+10)=0

x-7=0

x+10=0

x=-10

AB=x+5

AB=12

AB=-5

BC=x-2

BC=5

BC=-12

Area of ABC = 30cm2

Perimeter of ABC = AB+BC+AC

Solve the following equation for the variable indicated 15 = Зn + 6р, for n

Taya2010 [7]

Answer:

Solving the equation $15 = 3n + 6p$ for variable n we get $\mathbf{n=5-2p}$

Step-by-step explanation:

We need to solve the equation $15 = 3n + 6p$ for variable n

Solving:

$15 = 3n + 6p$

Subtract both sides by 6p

$15-6p = 3n +6p -6p\\15-6p=3n$

Switch sides of equality

$3n=15-6p$

Divide both sides by 3

$\frac{3n}{3} =\frac{15-6p}{3}\\n=\frac{3(5-2p)}{3}\\n=5-2p$

So, solving the equation $15 = 3n + 6p$ for variable n we get $\mathbf{n=5-2p}$
