Answer:
The Answer is: a^2 + 2ab + b^2
Step-by-step explanation:
Multiply the first factor resulting in the a squared, then the two inner factors resulting in ab + ab, finally the last term, resulting in b squared. Then combine terms:
(-a - b)(-a - b) =
a^2 + ab + ab + b^2 =
a^2 + 2ab + b^2
Hope this helps! Have an awesome day! :-)
Answer:
B
Step-by-step explanation:
For y to be a function of x, x must only have one value for each y value.
In B, the number 10 comes up twice in the x row. Therefore, y is not a function of x.
Answer:
300 ft²
Step-by-step explanation:
The area (A) of a rhombus can be calculated using
A =
× product of diagonals, thus
A =
× 24 × 25 = 300 ft²
Answer:
20
Step-by-step explanation:
The question is simply asking you to plug 6 into the function.


See diagram
so we got a right triangle
so for a right triangle, when we've got legs a and b and hytponuse c then
a²+b²=c²
so the legs are 90 and 90
hytponuse is distance from home to 2nd
so
90²+90²=c²
8100+8100²=c²
16200=c²
sqrt both sides
90√2=c
