23. Find the perimeter and area of the rectangle below. 10x^2 7xy^2​
coldgirl [10]

Answer:

Area= 70x^3y^2

Perimeter = 20x^2 + 14 xy^2

Step-by-step explanation:

Area is just multiplying the length and width, I multiplied the constants first which gets us 70 then multiplied the variables, they combine however only the x's can be multiplied to each other which results in 70x^3y^2 .  The perimeter you just multiply the length by two and the width by two, they are separate because the variables when added to each other do not combine.

If Andrea traveled 300 miles in 5 hours at what rate was she driving?
vladimir1956 [14]

Answer:

60 mph

Step-by-step explanation:

For this problem, we are looking at the rate, miles per hour. We know that Andrea traveled 300 miles in 5 hours, but how many miles did she travel in one hour? Let's do the math:

300÷5=60 miles.

So, in one hours, Andrea travels 60 miles. We get the rate, 60mph.

<u>Andrea was driving at 60 mph.</u>
