Answer:
3) f(x) = 3(x + 2)^2 - 1.
Step-by-step explanation:
f(x) = 3x² + 12x +11
f(x) = 3(x^2 + 4x) + 11 Completing the square:
f(x) = 3[(x + 2)^2 - 4] + 11
f(x) = 3(x + 2)^2 -+3*-4 + 11
f(x) = 3(x + 2)^2 - 12 + 11
f(x) = 3(x + 2)^2 - 1.

Triangles area is 40 cm^2 and the rectangles area is 437 centimeters squared I assume you mean triangle by the phrase tringe
Answer:
28 cm
Step-by-step explanation:
Given that :
Area = 791 cm
Base, b1 = 26.5 cm
Base, b2 = 30 cm
Area, A of trapezoid :
A = 1/2 (a + b) h
Where a and b are the bases ;
791 = 1/2(26.5 + 30)h
791 = 0.5(56.5)h
791 = 28.25h
h = 791 / 28.25
h = 28 cm
Answer:
The value of the variable 'b' is 3 and GH is 9
Step-by-step explanation:
Given:

H is between G and I
Such that G - H - I
To Find:
GH = ?
Solution:
On Substituting HI we get

Substituting 'b' in HI and GI we get


Now, by Line Addition Property we get

Substituting 'HI' and 'GI' we get

The value of the variable 'b' is 3 and GH is 9
