Answer:

h=3

Step-by-step explanation:

1 Remove parentheses.

6h+8-3h-2=156h+8−3h−2=15

2 Simplify  6h+8-3h-26h+8−3h−2  to  3h+63h+6.

3h+6=153h+6=15

3 Subtract 66 from both sides.

3h=15-63h=15−6

4 Simplify  15-615−6  to  99.

3h=93h=9

5 Divide both sides by 33.

h=\frac{9}{3}h=

Answer:

h=3

Step-by-step explanation:

So we have the equation:

(6h+8)-(3h+2)=15

First, let's distribute the negative:

(6h+8)+(-3h-2)=15

Combine like terms:

(6h-3h)+(8-2)=15

Subtract or add:

3h+6=15

Subtract 6 from both sides:

3h=9

Divide both sides by 3:

h=3

And we're done!

Draw and classify the polygon with the given vertices. Find the perimeter and the area of the polygon. M(-2,5), N(3,-2), P(-2,-2
Nadusha1986 [10]

Answer:

<em>Perimeter = 20.6cm  to 1dp  = 20.60cm to 2dp</em>

<em>Area = Base = 8.6/2 = 4.3 x 4.069  = 17.5cm^2</em>

<em>Height is found 4.07  cos( 54.47deg) 5/8.6 = 4.069cm</em>

Step-by-step explanation:

<em>Right angle side triangle, sides </em>

<em>= MN =8.6cm </em>

<em>= NP=5cm </em>

<em>= PM=7cm </em>

<em>= 25sq + 49sq = 74sq</em>

<em>MN^2 =√74 = 8.60232526704 = 8.6cm</em>

<em>P = 8.6 + 5 + 7 = 20.6cm </em>
