1. higher order thinking josh used
an algorithm to find the product for
9 x 239. his work is shown below.
is josh's work correct? explain.
239
x 9
1,800
270
+ 81
2,151

Yes.

Step-by-step explanation:

He correctly multiplies the 9 by each value in 239 and adds them up properly.

9 x 9 = 81

9 x 30 = 270

9 x 200 = 1,800

Then you would add these up to get 2,151

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

it would rotate about 180 degrees.
