Answers

Answer 1

Answer: You need to work this out using pythagoras' theorem.

Csquared=Asquared+Bsquared

But you are finding out A, not C, so you must rearrange the equation.

Asquared=Csquared-Bsquared
Asquared= 484-256
Asquared=228
A=Square root of 228
A=15 :)

Answer 2

Answer: the correct answer to your questin is 38

joe is preparing 18 hot dogs for his party. However, Joe only has 12 hot dog buns. How many more hot dog buns does Joe need?*

Answers

Its quite simple. Its just subtraction.
18 hotdogs - 12 hotdog buns = 6 hotdug buns still needed

18-12= 6
6 is the amount of hotdog buns needed.

You subtract 12 from 18 because you already have that amount of buns and need to see how many you need to get.

A square can be changed into a rectangle by increasing the width by 3 units. Which expression represents the area of the rectangle in square units? (A) x^2+8x+15 (B) x2+15 (C) 2x +8 (D) 2x+15

Answers

Letting x be the side-length of the square, the new rectangle has length x and width x+3. Thus, the area is (x)(x+3)=x^2+3x. This is not an answer choice.
