Answer:part a=4.6 part b=2.6
Step-by-step explanation:part a= first make sure to know which direction is which next you would end up making a triangle with the legs as 1.7 and 4.3 and use pythagorean theorem a^2+b^2=c^2 so 1.7^2 + 4.3^2= c^2 1.7^2=2.89 4.3^2=18.49 2.89+18.49=21.38 so now you square root 21.38 to get 4.62385 so it equals 4.6
part b = is basically the same thing except they gave you 3.1 as c and 1.7 as a so you would put it as c^2 - a^2=b^2 so 9.61 - 2.89= 6.72 then square root it to get 2.592296 which means it equals 2.6
OK, the square root of 250 is 15.811 . . .
but since this can't be expressed as a decimal for your purposes, let's try factoring. Since 250 ends in a zero, only numbers 5 or 0 or those ending in 5 or 0 could be factors.
The square root of 250 can be factored into the square root of 25 and the square root of 10.
The square root of 25 is exactly 5, and the exact square root of 10 is another decimal, so your simplified answer can be expressed as 5 times the square root of 10.
