Which expression can you simplify by combining like terms?

Mathematics
1 answer:
omeli [17]3 years ago

Answer:

The correct option is A.

Step-by-step explanation:

If the degree and variables of two terms are same, then they are called like terms.

In option A.

The given expression is  

12b^2+4ab-3ba-6

Here, 4ab and -3ab are like terms because both have same variables a and b with degree 1.

By combining like terms we get

12b^2+(4ab-3ab)-6

12b^2+ab-6

In options B, C and D, there are no like terms, So only the expression 12b^2+4ab-3ba-6 we can simplify by combining like terms.

Therefore the correct option is A.

Find the values for x and y.
vivado [14]
Both sides need to equal 180 (The side with the 90 degrees measurement and the side with equations). So first subtract 180 from 90
180 - 90
to get the measurement of 5x and you get 90 but we aren't done yet since we need to find x so now we need to divide 5 by 90
90 \div 5 = 18
and we get 18 which is X.
x = 18
Now we need to find the measurement of Y. Now both angles on that side together equals 180 so we need this equation.
5(y + 11) + 4y - 10 = 180
First, distribute 5(y + 11)
5 \times y \\ 5 \times 11
Then you get this equation :
5y + 55 + 4y - 10 = 180
Now, add the two equations together
5y + 55 + 4y - 10
and you get this equation

9y + 45 = 180
Now subtract 45 from both sides
9y + 45 - 45 = 180 - 45
and divide by 9 on both sides
9y \div 9 = 135 \div 9
and you get your answer
y = 15

So
x = 18
and
y = 15

Answer:

a)  C = 250 + 1.25n

b) 1800

c) 300

Step-by-step explanation:

a) To write the equation for these problems, let's establish the constant, $250, since we are given that $250 is a FIXED cost, meaning no matter how many brochures we print, we will have to pay $250. Then, we have to pay $1.25 for each brochure, so for n amount of brochures, so we have 1.25*n. Putting it together, we have the fixed cost + the cost of producing n brochures, C = 250 + 1.25C

b) The cost of printing 2500 brochures can be found by pluggin number into the equation above. C = 250 + 1.25*2500 = $1800

c) This is the opposite question, since 625 is the final cost, we plug it into the final cost, 625 = 250 + 1.25*n. Solving gives n = 300

A packing box is being filled with packing peanuts. The box measures 1 1/2 feet by 1 1/2 feet by 2 feet. How many cubic feet of
Stolb23 [73]

Answer:4.5\ ft^3

Step-by-step explanation:

Given

Measurement of box 1\frac{1}{2}\times 1\frac{1}{2}\times 2

suppose Length L=1\frac{1}{2}=\frac{3}{2}\ ft

Breadth B=1\frac{1}{2}=\frac{3}{2}\ ft

height H=2\ ft

Volume of Cuboid=L\times B\times H

Volume of Packaging box V=\frac{3}{2}\times \frac{3}{2}\times 2

V=\frac{9}{2}\ ft^3
