Thanks the line AB equals EF - what threw me off was EF looks at an angle - but I guess I assume since not drawn to scale - the 2 lines are the same.

For b) area of AEF so one side is 7 - don't know how to get other 2 sides not sure if right triangle; don't think so how to use the data given since two of sides are slanted

(3)42 = 84/2 so b times h equals 84

Not sure how to use a single area and line segments that are same to calculate the areas and line segments for the areas.

Thanks for the smaller triangle I get hypotenuse of 46.65. Then each leg and hypotenuse is multipled by a proportion? So larger triangle would be 50 leg - no idea how to figure height or hypotenuse unless I multiple by 10/40 percent all the known lengths.

In attached file, I understand 50 is the base; no idea how to use the 24 height to calculate length of ON - must have to do with property of right triangles?

Thanks, I got it a plus b = 154 154/2 = answer thanks for the equation

You got the problem correctly stated? x squared - x = 4 so not an integer without just randomly trying fractions, what other strategy? x squared = 4 - x? does not help

If average of 11 numbers is 14 and average of the 9 of those numbers is 9, what is the average of the other 2 numbers? Answer 36.5 9x9 = 81 - how do I write equation to figure out other 2 numbers without trial and error?

List contains 1, square root of 2, x and x squared and the list range is 4. I guessed 2 but it is not correct.
