SOMEONE PLEASE HELP WILL MARK BRAINLIEST PLEASE EXPLAIN
zalisa [80]

Answer:

a. (x+5)^2 = 49

b. (x+7)^2 = (x+1)^2

Step-by-step explanation:

So the term "a number" is always going to be x. input x into the sentences. "X plus five, then squared, is forty-nine". when they do "is __", that means equal to. In the second question, seven more than x is x + 7 (the two numbers are interchangeable here). Equivalent also means equal. hope this helped :)

dedylja [7]

Answer:

2323

Step-by-step explanation:

According to the questions above, the report from the traffic jam says the traffics jam stretches for 5.5 miles

As Connor assumes that each car is about 12.5 long

The next step is to convert 5.5 miles into feet.

Since 1 mile = 5280

To convert 5.5 miles, 5.5 x 5280 = 29040 feet  

To find the numbers of cars struck in traffic, we will have to divide 29040 by 12.5

29040/12.5 = 2323.3 ≅ 2323
