Answer:

B) n + 16

Step-by-step explanation:

We are given the expression 9 + 7 + n.

Here we need to simplify.

Simplify means we need to simplify the like terms.

Let's see what a like term is.

If we have the same variable with the same exponent, then they are called like terms.

The constants are the like terms, we can simplify them.

Examples:

2xy, -3xy are the like terms

5xy^2, -8xy^2 are like terms

4, 5, -7, 8 are the like terms.

In the given expression 9 + 7 + n

The like terms are 9 and 7. There are in the operation of addition. So we can add them.

So, 9 + 7 + n

= 16 + n

This can be written as n + 16 by commutative property of addition.

Therefore, the answer is B) n + 16

Length of the median CP
ehidna [41]

Given:

ΔABC \sim ΔDEF

To find:

The length of median CP

Solution:

In ΔABC,

AP = 12, BP = 12 and PC = 3x - 12

In ΔDEF,

DQ = 16, QE = 16 and FQ = 2x + 8

If two triangles are similar, then their median is proportional to the corresponding sides.

$\Rightarrow \frac{AP}{DQ} =\frac{PC}{FQ}

$\Rightarrow \frac{12}{16} =\frac{3x-12}{2x+8}

Do cross multiplication.

$\Rightarrow 12(2x+8)=16(3x-12)

$\Rightarrow 24x+96=48x-192

Add 192 on both sides.

$\Rightarrow 24x+96+192=48x-192+192

$\Rightarrow 24x+288=48x

Subtract 24x from both sides.

$\Rightarrow 24x+288- 24x=48x- 24x

$\Rightarrow 288=24x

Divide by 24 on both sides.

⇒ 12 = x

Substitute x = 12 in CP.

CP = 3(12) - 12

     = 36 - 12

     = 24

The length of median CP is 24.
