Answer:

It should be Like Terms

Explanation:

Like terms are the terms which have the same variables with same exponent for each variable.

Example :

7x, 3x, - 4x

Unlike terms are the terms which have same variables or different variables.

If they have same variables, the exponents will not be same.

Example :

9x2, 5xy, - 4xy2, y, 6

I need help with this one math question please!

Answer:

see explanation

Step-by-step explanation:

Assuming the fractions are being multiplied

Factorise the denominators of both fractions

x² - 3x - 10 = (x - 5)(x + 2)

x² + x - 12 = (x + 4)(x - 3)

The product can now be expressed as

$\frac{x-5}{(x-5)(x+2)}$ × $\frac{x+2}{(x+4)(x-3)}$

Cancel (x - 5) and (x + 2) on the numerators/ denominators, leaving

$\frac{1}{(x+4)(x-3)}$ = $\frac{1}{x^2+x-12}$

15 tens is the same as

Eduardwww [97]

"tens" can be represented in numbers as "10"
15 tens means that you will multiply 15 by the tens (multiply 15 by 10).

Based on this:
15 tens = 15 x 10 = 150

Therefore:
15 tens is equivalent to 150

Rounded to the nearest whole number, how many 2ft by 2ft squares will fit into circle that has a diameter of 20 feet?

seraphim [82]

Answer:

Step-by-step explanation:

The area of a circle is pi*radius^2; the radius of this circle is 10 (20/2=10). Our area is then 100pi or ~314 square feet. A 2x2 square takes up 4 feet. 314/4 is equal to 78.5, or when rounded, 79
