The square of the sum of 7 times x and 3 divided by 4 times the difference of c and 1

Step-by-step explanation:

The square of the sum of 7 times x and 3 divided by 4 times the difference of x and 1

Convert the verbal statement into an expression

sum of 7 times x  and 3 become 7x+3, for sum we add

for square we put exponent 2, square of the sum (7x+3) becomes (7x+3)^2

differeence of x and 1 is x-1

4 times the difference means we multiply by 4

it becomes 4(x-1)

The square of the sum of 7 times x and 3 divided by 4 times the difference of x and 1

(7x+2)^2 divide by 4(x-1)

step-by-step explanation:

most likely the answer is a.

alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
