Answer:
294 square units
Step-by-step explanation:
35^2-21^2=a^2
a^2=784
square root 784=28
21*28/2=294
Answer=294
Answer:
two
Step-by-step explanation:
A ratio compares the relative sizes of two quantities .
Answer:
x=2
Step-by-step explanation:
F(x) = 2x^2 - 8x +8
Axis of symmetry lies at the x coordinate of vertex
To find x coordinate of vertex use formula

from the given f(x) , a= 2 and b = -8
Plug in all the values


x=2
So the axis of symmetry at x=2
Answer:
5y + 4 and 7y + 4 - 2y
Step-by-step explanation:
Look at the second choice:-
5y + 4 and 7y + 4 - 2y
Simplifying the second expression:-
7y + 4 - 2y
= 5y + 4
So both expressions are equivalent . Therefore if you plug in 2 or 5 the results will be the same.
Answer:
D. |C -305,000| ≤ 80,000
Step-by-step explanation:
Such an equation will say that the difference from the average of these values is at most half of their difference.
| C -(225000+385000)/2 | ≤ (385000 -225000)/2
|C -305,000| ≤ 80,000 . . . . . matches choice D
