Answer:
3
Step-by-step explanation:
The terms of this given expression are 3x^2, 4y and 1.
Thus, there are three terms.
Answer:
x = 4, x= -8
Step-by-step explanation:
To start, let's define our variable, which is x. x will represent the width of the rectangle. Next, since you know that the length is 4 times as long as the width, it will be represented by 4x. Now, since you know that the perimeter of a figure is the sum of the length of all the sides of the rectangle, you can express the perimeter with this expression: 4x+4x+x+x
Then, you set the expression to the perimeter, which is 110.
4x+4x+x+x=110
Combine like terms: 10x=110
And solve for x: x=11
Now that you have solved for x, which represents the width of the rectangle, you now know that your answer is 11.
In order to calculate correctly, it is important that we are able to understand well the given values. We have
3/4 yard fabric = total amount of available fabric
3/10 yard= amount needed to make one doll
Therefore,
number of doll dresses = 3/4 / 3/10 = 2 doll dresses
