Do the ratio of the two sides. To get the area square the two sides.
(9/15) ratio of sides
(9/15)^2 ratio of areas
81/225
Multiply for the known area
90*(81/225) = 162/5 = 32,4 sq. inches (area of corresponding triangle)
Answer:
The discriminant is:
b
2
−
4
a
c
a
=
1
b
=
12
c
=
36
Substitute these values into the discriminant and you should get two answers (real roots):
12
2
−
4
(
1
)
(
36
)
=
0
If the discriminant is 0 there is 1 real root, if it is > 0 there are 2 and otherwise 0 real roots.

Im pretty sure this is it, hope I could help
Volume of an iceberg = 7685 cubic feet
Since, density of ice = 0.917 
We have to determine the mass of the ice.
Since density = 
Since the unit of density is in
, first we will convert the density unit in kilogram.
Since, 1 kilogram = 1000 gram
Therefore, density = 
= 0.000917 
Since, the density unit is in cubic centimeter. We will convert it into cubic feet.
1 cubic centimeter = 0.00003531466 cubic feet
Therefore, 0.000917
= 0.000917 x 0.00003531466
= 0.0000000323
.
Now, mass = 
= 0.0000000323
7685
= 0.000248
=0.00025
.
Therefore, the mass of ice is 0.00025
.
Answer:
Its Option C.
Step-by-step explanation:
-4x + 7 = 2y - 3
Substitute the given values in the given equation:-
(2,1):- -4(2) + 7 = -1 and 2(1) - 3 = -1 so (2,1) is a solution.
(5, -5):- -4(5) + 7 = -13 and 2(-5) - 3 = -13 so (5, -5) is also a solution.
Answer: B
-3 x 4x = -12x
-3 x -0.50 = 1.50
-12x + 1.50
Hope this helped! :D
