Let
be the height of the triangle.
Formular for area of Triangle
= ½ × base × height
thus,
Simplifying
Ok....
Simplified would be 12.40
Squared would be 153.99 or fraction form would be 83 + 12

3-4x=-6x^2
+6x^2=+6x^2
_____________
6x^2+3-4x=0
6x^2-4x+3=0
(-4)^2-4(6)(3)
16-72
Final Answer: -56
-9/5 or -1.8
2 - - 3 = 5
-5 - 4 = -9
Answer:
a. 7.2
b. 6
Step-by-step explanation:
Since the side lengths of similar polygons are proportional to each other, therefore:

Thus, let's find b using:

Cross multiply


Divide both sides by 15
b = 6
Let's find a using:

Cross multiply
9*12 = 15*a
108 = 15a
Divide both sides by 15
a = 7.2
