The correct answer is A. rational expression

Rational expression refers to a fraction in which the numerator and denominator are polynomials. Polynomials are variables. So therefore rational expression is the answer to the term that describes a fraction that has a variable or variables expression in its numerator and it denominator or both.

Answer: the term described a fraction that has a variable or variable expression in its numerator is called the rational number

Explanation:

Rational number is basically the quotient of two integers and the denominator is not zero (remember that you can never divide by zero; if you do the answer always will be infinity)  

For example:

1 divided by 3 = 1/3 is a rational number

-5 divided by 8 = -5/8 is also a rational number

Sam said shape A has a uniform cross section. Lloyd said shape B has a uniform cross section. Who is correct? Explain your answe
STatiana [176]

Answer:

Sam is right. shape A which is cylinder has uniform cross section.

Explanation:

what is uniform cross section?

uniform cross section is when cut through an object and the bases are similar.

solution:

For cylinder:

when we cut a cylinder, its in a circle shaped and have similar bases - thus have uniform cross section.

For pyramid:

when we cut a pyramid it is in rectangle shape and this changes as we go up or down the pyramid and does not have uniform cross section.

Answer:

-35 - 5

Step-by-step explanation:

2 + 12 = 14, which is positive

(-3) * (-8) = 24, which is positive

10 - (-18) = 10 + 18 = 28, which is positive

-35 - 5 = -40, which is negative

3. well you know to get the perimeter of a rectangle, you add together 2L and 2W. A way you could write this is-- 2x + 2(x+5). You would just need to simplify it--2x + 2x+10 --4x+10.
4. To find out how much they have in all, you just need to add them together--x+24.50 + 7x-52.34. Now you need to simplify the problem by putting the values together. x+7x + 24.50-52.34-- you can do that.
5. To do this one, look back at 3. and just change the numbers. Drawing a picture may help. The sides are x+y and the top and bottom are 5y+12.
6. same as 5.
7. I think this one is just solving for x first. make Tom and his brother's equations equal to zero and get x by itself. Tom's equation would be 8x-30=0 ----His brother's would be 5x+10. You need to find out what x equals then plug it back into the equations. To plug it in, have x's value take x's place then find the number of candies they have. 
8. The easiest way to start is by writing the same values together. 4x+3x-5x-5-7+2---then just add the x's together and add the numbers together. 
9. Multiply the outer numbers to both of the values in the parentheses. 2(x-4) would turn out to 2x-8. then do the same as 8. and put the same values together to simplify. 
10. get x by itself. Start by multiplying 3 by x and 4 in the parentheses. simplify the numbers then subtract it from both sides to get x alone.
