n triangle have n x 1/18 m^{2}

To composed an area of 3/2 m^{2} we need to get 27 triangles each having an area of 1/18 m^{2}

Which equation shows the quadratic formula used correctly to solve 7x2 = 9 + x for x?
Aleonysh [2.5K]
For future reference, use a * to show the multiplication sign because in math x is a variable. 7*2 = 9 + x

Now multiply 7*2= 14

14 = 9 + x

Now subtract 9 from both sides to isolate the x

A candle is lit and the length of the burning candle changes at a constant rate of -1.6 inches per hour. 3 hours after the candl
Gnesinka [82]

Answer: The length of the candle was 13.5 inches before it was lit.

Step-by-step explanation:

Let the length of candle in the beginning be c.

Constant rate of change in length of candle=  -1.6 inches per hour

Since rate of change is constant so the length of candle can be represented by a linear function [Linear function has constant rate of change.]

Linear function : f(x)= mx+c , where x= independent variable.

m= constant rate of change and c= initial value of function.

Let x = Number of hours after the candle was lit.

Put m=  -1.6 , x= 3 and f(x)= 8.7 , we get

8.7=-1.6(3)+c\\\\ 8.7= -4.8+c\\\\ c=8.7+4.8=13.5

Hence, the length of the candle was 13.5 inches before it was lit.
