Answer:
Step-by-step explanation:
Some qucik lil definitions of these words
<em>Coefficient </em>- A multiplicative factor in some term of a polynomial, a series, or any expression.
<em>Constant </em>- A value that is unchanging.
<em>Term </em>- A single mathematical expression.
<em>Variable </em>- A letter used to represent an unknown.
Step-by-step explanation:
The third option: 5x(x^2+3)(4x-5)
because FOIL first, inner, outter, last
The two parentheses become (4x^3-5x^2+12x)
then 5x outside multiplys that whole parentheses. To get your correct expression
Answer:
C. 5
Step-by-step explanation:
Keeping in mind that this is a right triangle, to find the length of side a, we can use the Pythagorean Theorem.
Remember, the Pythagorean Theorem is:
a² + b² = c²
where a and b are the legs of the right triangle and c is the hypotenuse.
As we can see in the image, a is one of the two legs of the right triangle. 13 is the hypotenuse and 12 is another leg. Plugging into the Pythagorean Theorem, we get:
a² + 12² = 13²
Now we solve for a.
a² + 144 = 169
Subtract 144 from both sides.
a² = 169 - 144
a² = 25
Take the square root of both sides.
a = √25
a = 5
So the length of side a would be 5.
The answer would be C. 5.

Answer: House = 550 and Porch = 325
Explanation:
Porch = (30 x 15) - [(30 + 20)5/2]
Porch = 450 - 125
Porch = 325
House = (30 x 10) + 2(125)
House = 300 + 250 = 550
