Answer:

2a - b = 5

Step-by-step explanation:

4a - 2b = 10

take out the highest common factor of the left side

2(2a - b) = 10

divide both sides by two

2a - b = 10/2

2a - b = 5

Answer:

350.82

Step-by-step explanation:

To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.

The rectangle's area (lw):

7.21*14=100.94

The triangle's area (\frac{1}{2}bh):

\frac{1}{2} (6)(8)

\frac{1}{2} (48)=24

Now add up all the sides. (3 Rectangles, 2 Triangles.)

100.94 + 100.94 + 100.94 + 24 + 24

=350.82

The total surface area is 350.82 cm squared.

Please, post just one problem at a time, or (if you post more than one), indicate which one you want to focus on first.  Even more important, please do whatever you can to get started on each problem; I'm sure you know at least some basics.

What does "intersecting" mean?  Look it up if you're not sure.

Then what would "two intersecting lines" look like?  Draw the graph, or at least explain in words what the graph would look like.

If f(x)=4-x^2 and g(x) =6x which expression is equivalent to (g-f)(3)
MArishka [77]

Answer:

-18

Step-by-step explanation:

Given:

f(x)=4-x^2 and g(x) =6x

h(3) = (g-f)(3)

= 6x - (4x^2)

= 6*3 -(4*3^2)

= 18 - 4*9

= -18

How does the value of a decimal changes as you move to the left or the right in a place value chart
icang [17]
If you move it to the left the number would increase so for example you had 2.3 and you move it to the left then it would be 23, so if you times it by tenth or hundredth then it would go to the left but if you divide then it would go down so moving to the right would get you 0.23
