Step-by-step explanation:
<h2>
<em>If they are different, rewrite one or both fractions with a common denominator. Step 2: Check the numerators. If the denominators are the same, then the fraction with the greater numerator is the greater fraction. The fraction with the lesser numerator is the lesser fraction.</em></h2>
In this problem, you must change the signs of everything in the parenthesis, which will come to 3x^2 + x - 5x^2 - x + 4. Add like terms, and you will end up with -2x^2 + 4, which is answer choice A. Hope this helped
Answer:
C 12
Step-by-step explanation:
they are proportionate, so right side = 11 and bottom = 22
11-5 = 6 = other length on right
6 x 2 = length ?
lenth ? = 12
Answer:
area of circle=π
452.1=3.14
452.1/3.14=
143.98=
=r
11.99=r
now ,
diameter=2r
=2*11.99
=23.98
Step-by-step explanation:
Saying arccos(-√2/2) is the same as saying cos(x)=-√2/2. This is one the trigonometric values you should have memorized if you are taking a a trig class. In order to get √2/2, x must be equal to 45° or pi/4. But since it is a negative √2/2, the answer would be -45°or -pi/4.
There are technically multiple answers to this, but since you weren't given a range for the answers, I would stick with -45°.
Hope this helps
