Answer:
answer is B
Step-by-step explanation:
Answer:
unlike terms
Step-by-step explanation:
since the first 9y is squared they cannot be combined since the other isn't squared, they cannot be simplified, nor are they alike
Area of the triangle at the top=1/2basexheight
1/2x10x 2= 10
Area of rectangle =length xwidth
9x10=90
Total area =area of triangle +area of rectangle
90+10=100m^2
We know that in this type of triangle that the hypotenuse is √2 times the length of either leg
in our case the hyp=5√2
