Answer:
c = 169
Step-by-step explanation:
We can use FOIL to determine this after factoring out the equation.
(x+13)(x+13)
F: (x*x)
O: (x*13)
I: (13*x)
L: (13*13)
x^2 + 26x + 169
Answer:
Science Test
Step-by-step explanation:
Math test:
24/30 so divide 24 by 30 to see the percentage she got, which is 80%
Science test:
21/25, same process as before, 21 divided by 25 is 84%
Therefore, she scored higher on the science test.
we have

we know that
1 quarter is equal to 0.25 gallon
1 hour is equal to 60 minutes
convert
to 

therefore
the answer is

Answer:
Distance = 7.8 units
Step-by-step explanation:
In coordinate geometry, the distance between the 2 points is given by

where (x1,y1) and (x2,y2) are coordinates of the 2 points.
Above the 2 points given are, (-2,-1) and (3,5).
<em>x1 = -2 , y1 = -1 , x2 = 3, y2 = 5</em>
<em>
</em>
<em>
</em>
<em>Distance = 7.8102 units</em>
To the nearest tenth, Distance = 7.8 units
