Like terms are those terms, which have the common variable with same powers.

The number of like terms in the given expression are 3, which is (14x,-x,2x). the option 3 is the correct option.

<h3>What is like terms?</h3>

In the algebra or the algebraic expression the like terms are those terms, which have the common variable with same powers.

Given information-

The given expression in the problem is,

14 x -14 y+ 7 - x+ z+ 2 x

The given expression is the algebraic expression which 3 number of unknowns variables.

There is total 6 terms in the given expression. In which 5 terms consists the variables and one term is constant.

In the given expression,

  • The total number of terms with variable x are 3 which are,(14x,-x,2x).
  • The total number of terms with variable y is 2 which is -14y.
  • The total number of terms with variable z is 1 which is z.
  • The total number of constant terms is 1 which is 7.

Thus the number of like terms in the given expression are 3, which is (14x,-x,2x). the option 3 is the correct option.

Hannah is designing containers to hold 300 cm3 of juice. Which container is more efficient?
Lubov Fominskaja [6]

Answer:

a) 2nd container is more efficient and contains the elements for a container.

b) The cylinder has a........A)Smaller surface area B)bigger C)equal

And will cost.....A)Less to produce B)more C)The same

Step-by-step explanation:

a) The 2nd container has these elements:

Width 20.5cm

Length 6.5cm

side 3.25cm

So, the volume in cubic cm is 20.5 x 6.5 x 3.25 = 433cm3.

This container can hold the 300cm3 of juice.

b) A cylinder is a geometric solid common in everyday life.  Examples of a cylinder are soup cans, food tins, drink cans, candles, toilet paper rolls, cups, aerosol cans, flower vases, test tubes, fire extinguishers, plant containers, salt shakers and pencil holders.  The two ends are called bases, and are usually circular.  Though, they can take other shapes.  When a cylinder is unrolled and flattened out, the side is actually a rectangle.

The surface area of a cylinder is the surface area of each end plus the surface area of the side.  The mathematical formula is 2π * r2, where π is the pie and r is the radius of the end and r2 is r squared..
