Answer:

a) g(3) = <u>9</u>

b) g(-1) = <u>1</u>

c) g(-x) = <u>x²</u>

d) g(2y) = <u>4y²</u>

e) g(1+h) = <u>1 + 2h + h²</u>

Step-by-step explanation:

a) <em>when </em><em>x = 3 ,</em>

   g(3) = 3² = <u>9</u>

b) <em>when </em><em>x = -1 ,</em>

   g(-1) = (-1)² = <u>1</u>

c) <em>when </em><em>x = -x ,</em>

   g( -x ) = (-x)² = <u>x²</u>

d) <em>when </em><em>x= 2y ,</em>

   g( 2y ) = (2y)² = <u>4y²</u>

e) <em>when </em><em>x = 1 + h ,</em>

   g( 1 + h ) = ( 1 + h )² = 1 + 2h + h<u>²</u>

Step-by-step explanation:

a)

<u>g(3) = 9 </u>

b)

<u>g(-1) = 1</u>

c)

<u>g(-x) = x²</u>

d)

<u>g(2y) = 4y²</u>

e)

<u>g(1 + h) = 1 + h² + 2h</u>

How do you solve 7.5=x+3/2
labwork [276]
7.5 = x + \frac{3}{2} equals x = 6.

First, subtract \frac{3}{2} from both sides. / Your problem should look like: 7.5 - \frac{3}{2} = x.
Second, simplify 7.5 - \frac{3}{2} to 6. / Your problem should look like: 6 = x.
Third, switch sides. / Your problem should look like x = 6, which is your answer.

The figure below is a net for a triangular prism. Side a = 45 inches, side b = 14 inches, side c = 30 inches, and altitude d = 2
katrin [286]

Answer:

the answer is A.  2370 sq. in

Step-by-step explanation:

area of the triangles first

A = 1/2 ad

a = (45 in) (20 in)

a = 1/2 (900 sq in)

a = 450 sq in

***remember to multiply 450 * 2 because you have 2 triangles***

Total area of both triangles is 900 sq. in.

Find the area of the 3 rectangles A = LW

1st rectangle and 2nd rectangle

a = cb

a = (30 in) (14 in)

a = 420 sq in. (make sure you add this again in the Total Surface area)

3rd rectangle

a = ab

a = (45 in) (14 in)

a = 630 sq. in

Total Surface area = 2 (1/2 ad) + 2(cb) + (ab)

= 2 (450 sq. in) + 2 (420 sq. in) + 630 sq. in

= 900 sq. in + 840 sq. in + 630 sq. in

= 2370 sq. in
