C.15/18=25/30 because 15/18=150/180 and 25/30=150/180
those two fractions are equal as we can see
There are two ways to solve the problem: using calculus and algebra. For this, I'll be using the algebraic way. The function is parabolic, thus the minimum value is the ordinate of the vertex. Using completing the square, we could get the vertex of the parabola.
y = x^2 + 4x - 5y = x^2 + 4x + 4 - 5 - 4y = (x + 2)^2 - 9Vertex is (-2, -9).
Therefore, the minimum value is -9.

Answer:
18 and 52
Step-by-step explanation:
x + Y = 70
X - Y= 34 find the value of X interms of Y to find the answer:
X - Y= 34
X = 34 +Y
x + Y = 70
(34 + Y ) + Y = 70
34 + Y +Y = 70
2Y =70-34
2Y/2=36/2
Y = 18
x + 18 = 70
x=70 - 18
x= 52
check:
18 + 52= 70
52 - 18= 34
Answer:
84 mm^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 b *h
The base is 14 and the height is 12
A = 1/2 (14*12)
A = 84 mm ^2
