A rectangle with sides 4 in. and 7 in. was enlarged in the ratio 1:2 How did the area of the rectangle change?
a. became 28 sq. inches bigger
b. became 4 times as large
c. became twice as large
d. remained the same as it was before

Step-by-step explanation:

The volume of a rectangular box is given to be 2

3 − 2

2 − 44 + 80.

If the length of the box is given to be x+5, what are the dimensions

of the rectangular base of the milk box? Show the complete

solution.

A. (2 − 3)( − 3)

B. (2 − 8)( − 2)

C. (2 + 8)( + 2)

D. ( − 8)( − 2)

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

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
