Trec is a rectangle. what is the length of et?

Answer

Find out the length of ET .

To prove

As given

TREC is a rectangle.

Thus in the rectangle each diagonal bisects the other i.e divided each other in the two equal parts .

Thus CR is divided into 2x-3 and x + 7 .

2x - 3 = x + 7

x = 10

CR = 2x-3 + x + 7

     = 2 × 10 - 3 + 10 + 7

    = 34 unit

As in the rectangles diagonals are of equal length .

CR = ET

ET = 34 unit

Therefore the value of ET is 34 units .

Option (d) is correct .

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
