PLEASE HELP ME RN PLEASE ​
Advocard [28]

Answer:

1.

\frac{n^{2} - 1 }{2}

2.

\sqrt{29}

Step-by-step explanation:

Area of triangle=1/2×b×h

=

\frac{1}{2}  \times (n - 1)(n + 1)

\frac{( {n}^{2} + n - n - 1) }{2 }

\frac{ {n}^{2} - 1 }{2}

2. Area of triangle=14

\frac{ {n}^{2} - 1 }{2}  = 14

{n}^{2}  - 1 = 28

{n}^{2}  = 29

n =  \sqrt{29}

The function h is defined by h(x)=4+3x over 5+x<br><br> Find h(4z)
Jobisdone [24]

Answer:

h(4z)=4+12z / 5+4z

Step-by-step explanation:

The function h is defined by h(x)=4+3x over 5+x

This can be written as

h(x)=4+3x / 5+x

The value of the function at any time depends on the value of x. x is the independent variable. The variable,x can take any value at any time.

To find h(4z), it means that x is taking the value of 4z.

We will substitute 4z in the place of x in the function. This becomes

h(4z)=4+3×4z / 5+4z

h(4z)=4+12z / 5+4z
