Step-by-step explanation:
area of the triangle
1/2xbxh
1/2(12x9)
1/2(108)
area of triangle is 54in²
area of rectangle
2(L+W)
2(15+6)
2(21)
area of rectangle is 42in²
Total area is 96in²
25² = ( 20 + 5 )² This is the square of a binomial:
( a + b )² = a² + 2 a b + b²
625 = 20² + 2 · 20 · 5 + 5²
625 = 400 + 200 + 25
625 = 625 ( correct )
<span>When
a data value is converted to a standardized scale representing the
number of standard deviations the data value lies from the mean, we
call the new value a z-score.
A z-score is used to indicate how many standard deviation a value is from the mean.

Answer:
The third answer option is correct. sqrt(x) = x^(1/2). So sqrt(121) = 121^(1/2)
Answer:
Step-by-step explanation:
If u = 6 then substitute so
6(6+6)=6 know solve but this isn't going to be correct because 6 plus 6 is 12 times 6 isn't 3
So your answer isn't correct. I think it would be a negative number or decimal because 6 is larger than 3. Hope this helps!
it is u(u+6)=3
I got u=6
