Write an expression, involving exponents to represent the shaded area, in square inches of the diagram.

Step-by-step explanation:

We have got 3 squares here. The shaded area is not clear but it is an understood fact that the question must be asking about the area in the bigger square minus the sum of smaller 2 squares.

So, the area of the bigger square is = (exponent form)

or 36 square inches

Area of smaller square with side 3 inches = (exponent form)

or 9 square inches

Area of second smaller square with side 2 inches =  (exponent form) or 4 square inches.

Sum of the area of smaller squares = = 9+4 = 13 sq inches

And area of the shaded region will be = 36-13 = 23 square inches.

In exponent form it can be written as :

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
