The area of a triangle is 16 square units. The base of the triangle is four more than the height of the triangle. What is the ba

sukhopar [10]

Let x=height. then base is x+4. plug what we know into the formula for the area of a triangle

A=½bh

16=½*(x+4)*(x)

32=x²+4x

x²+4x-32=0
(x+8)(x-4)=0
so x can be-8 our 4. when we plug-8 in for x we get a negative height. since a triangle cannot have a negative side length we discard-8 and try 4. height=4 and base=8

Leo had $91, which is 7 times as much money as Alison had. How much

NARA [144]

Answer:

$7x=91$

$13.

Step-by-step explanation:

Let x represent money that Alison has.

We have been given that Leo has 7 times as much money as Alison had. So the amount of money that Leo has, would be $7x$ .

We are also told that Leo had $91, so we will equate $7x$ with 91 and solve for x as:

$7x=91$

To solve for x, we will divide both sides by 7:

$\frac{7x}{7}=\frac{91}{7}$

$x=13$

Therefore, Alison has $13.
