Answer:
x*(3x^2-7x-24)
Step-by-step explanation:
The car is traveling at 40 miles per hour (mph) and the distance it has traveled is 81 miles. You can use the distance equation, which is d = rt, where d stands for distance, r stands for rate of travel/speed, and t stands for time.
In this case, you will substitute in your known values and solve for the variable you don't know:
d = rt
81 = 40t
To find out how long it takes for the car to travel 81 miles at a rate of 40mph, you will need to solve for the variable (t), which stands for time.
Answer:
I think they are asking the area of the triangle so we are going with that.
Step-by-step explanation:
Easiest way to do this is find the area of the incomplete square, and then cut that in half for the triangle.
so it is 4 cm wide
and 8 cm tall
length x width = area
8 x 4 = 32
32/2 = 16
So your answer should be 16 cm
Answer:
