It is the first choice. 3 times 5/2 is 15/2 which equals 7.5 and 12 times 5/2 is 60/2 which equals 30. 7.5 times 30.
Answer:
Assuming the 2 at the ends are the exponents,
the answer is -x^2-5x+6 (x^2+5x-6)
from here, it cannot be simplified more
Explanation --
Just add everything by putting the terms in parentheses and adding them.
Keep simplifying by putting the like terms together and adding/subtracting them.
At the end, you come up with -x^2-5x+6, so multiply -1 on the whole thing (by putting parentheses on its sides. This makes x positive. But they are the same thing, but this step is just for simplifying the end product a little more.
Hope this helps!! Have a nice day!
Answer:
16 = a
Step-by-step explanation:
6 = a/4 +2
Subtract 2 from each side
6-2 = a/4 +2-2
4 = a/4
Multiply each side by 4
4*4 = a/4*4
16 = a
X is amount of books.
x ≤ 9 if the books are 2 inches thick.
x ≤ 18 if the books are 1 inches thick.
Equation for 1 inches.
x ≤ 18
Equation for 2 inches.
2x ≤ 18
Equation for both.
x + 2y = 18
y is amount of 2 inch books
This one equation above is standard form.
Answer:
r = 2 units
Step-by-step explanation:
Radius of a circle is 1/2 its diameter.
Given the diameter of circle as 4 units ,
radius r = 1/2 x 4
= 4/2
= 2 units
