The base of a triangle is seven more than twice the height. The area of the triangle is 135 square meters. Find the measures of
the base and height of the triangle.
1 answer:
Answer:
Height = 10 m
Base = 27 m
Step-by-step explanation:
The base of a triangle is seven more than twice the height
The area of the triangle is 135 m²
Height = x
Base = 2x + 7
Area of a triangle = 
× base × height
∴
× (x) × (2x + 7) = 135
2x² + 7x - 270 = 0
Applying the quadratic formula we get;
x = 10 or -13.5
Since we can't have a length being negative, the height of this triangle is 10 m
The base = 2(10) + 7 = 27

G(x)=4x^2-3x+7
g(3)=4(3)^2-3(3)+7
g(3)=34
C. point K is (3,-3) and the dilation moves from 3 to 1 so you divide both X and Y coordinates by 3 to get (1,-1)
hope this helps.
No because 7-4 would be 3, then 3/3 is just 1 so the answer would be x=1
Answer:
Step-by-step explanation:
c^2 = a^2 + b^2
4.5^2 + 9^2 = 101.25
c = sqrt 101.25 = 10.06 = 10.1 meters
