The height of a triangle is 2 less than 5 times its base. If the base of the triangle is x feet, and the area of the triangle is
Gnesinka [82]

Answer:

A. 5x^2 − 2x − 24 = 0

Step-by-step explanation:

height = 5b-2

b =x

We can rewrite the height as

h = 5x-2

We know the formula for area of a triangle

A = 1/2 bh

A =1/2 x * (5x-2)

Distributing the x

A=    1/2 (5x^2 - 2x)

We know A =12

12 = 1/2 (5x^2 - 2x)

Multiply each side by 2

12*2 = 2*1/2 (5x^2 - 2x)

24 = 5x^2 - 2x

Subtract 24 from each side

24-24 = 5x^2 - 2x-24

0 = 5x^2 - 2x-24

G(n) = 4n+5 f(n)= n^3+3n^2 find (g+f)(n)
Tpy6a [65]

Given:

The two functions are:

g(n)=4n+5

f(n)=n^3+3n^2

To find:

The function (f+g)(n).

Solution:

We have,

g(n)=4n+5

f(n)=n^3+3n^2

Now,

(f+g)(n)=f(n)+g(n)

(f+g)(n)=n^3+3n^2+4n+5

Therefore, the correct option is B.

Answer:  

y = 4x² -19x -5

Step-by-step explanation:  

When you graph it (or use an appropriate tool), it can help us to figure out that the equation is:

y = 4x² -19x -5

(Quadratic regression = the process of determining the equation of a parabola that best fits a set of data)

What are the dimensions
kobusy [5.1K]

Answer:

456 sq. units

Step-by-step explanation:

Formula for the area of the square:

b(base)*h(height)

b=21

h=16

21*16=336

Formula for the area of the triangle:

b*h/2

b=36-21=15

h=16

15*16/2=120

Add the two shaped together:

336+120=456

Label your answer: 456 sq. units
