Answer: B

Step-by-step explanation:

Perimeter = 2(length+width)

'CD' = 20×cos(30) = 17.3205

width 'AD' = 20×cos(60) = 10

Perimeter = 2(17.3205+10)

= 2(27.3205)

= 54.641 =54.6

What will be the result of substituting 2 for x in both expressions below? One-half x + 4 x + 6 minus one-half x minus 2 Both ex

Anit [1.1K]

Answer:

Both expressions equal 5 when substituting 2 for x because both expressions are equivalent

Step-by-step explanation:

Given

$\frac{1}{2}x + 4$ - Expression 1

$x + 6 - \frac{1}{2}x - 2$ -- - Expression 2

Required

Find the result of both expressions when $x = 2$

Expression 1

$\frac{1}{2}x + 4$

Substitute $x = 2$

$\frac{1}{2} * 2 + 4$

$1 + 4$

$Result = 5$

Expression 2

$x + 6 - \frac{1}{2}x - 2$

Substitute $x = 2$

$2 + 6 - \frac{1}{2} * 2 - 2$

$2 + 6 -1 -2$

$Result = 5$
