5 0

Answer:

12

10(3w)=6*5

30w=30

w=1

(not sure if youre meant to just have the equation or find w)

13

48°F

14

€1.25

Step-by-step explanation:

12

The floor area is found by multiplying its length by its width: 6*5=30

The amount of area covered by one tile is found by multiplying its length by its width: 3*w=3w.

Ten tiles are used to cover the floor, so the floor area should be equal to ten times the tile area:

10(3w)=6*5

30w=30

w=1

(not sure if youre meant to just have the equation or find w)

13

35°F is 13°F lower than the high temp. So, add 13°F to find the high temp.

35+13=48°F

14

Sixteen bagels cost €20. To find the price of one, we divide the price by the amount bought: 20/16=1.25

If f(x)=2x+5 , determine the value of f(3x) .
makvit [3.9K]

Answer:

Step-by-step ef(x)=-2x+5……i

and f(-3x)=?

let x=-3x so that

-2x+5=-3x

x=5

substitutinx x into… i

f(x)=-10+5=-5

f(5)=-5………ii

now f(–3x)=f(-15)

scrutinizing… ii ,we can propose that

f(-15)=15.

Thus f(-3x)=15xplanation:

Which combination of shapes can be used to create the 3-D figure?
liq [111]

Two regular octagons and eight congruent rectangles are perfect for the creation of 3-D figures.

According to the statement

we have to tell and explain about the types of shapes which are required for the creations of 3-D figure.

For this purpose, Firstly we have to know about the 3-D figures.

So,

A shape is a graphical representation of an object or its external boundary and outline, as opposed to other properties such as color, texture, or material type.

A plane shape is constrained to lie on a plane, in contrast to solid 3-D shapes.

After that we know that the

When the all dimensions of a given shape can be observed at the same time, then its is said to be in a 3-D. However, polygons are shapes which has 3 or mores sides. Examples are: trigon, hexagon, octagon etc.

Thus, since the in the 3-D figure have 8 sides connected which is greater than their width.

This confirms that the sides of the figure made up of eight congruent rectangles, because the 3-D figure has eight regular sides. Then, the height of the figure would be the length of the rectangles.

After that all this condition, Two regular octagons and eight congruent rectangles are perfect for the creation of 3-D figures.
