12. (x-√3)(x+1) = x² + (1-√3)x - √3
13. (x+2)(x²+4) = x³ + 2x² + 4x + 8
14. (3x³ + 6x² - 5x + 12) ÷ (x-3)
= [(x - 3)(3x² + 15x + 40) + 132 ] ÷ (x-3)
Quotient = 3x² + 15x + 40
Remainder = 132
The answer is d.
First you have to divide 160/ 1/4. So you would do 160/1 divided by 1/4. Because of keep, change and flip. (k.c.f) you would keep 160/1, change the division sign, then flip 1/4 to 4/1. Then you multiply 160/1*4/1. Then you would get 640. Hope this helped.
Think about it think 6x5 or higher then you will get you answer by doing that
Answer:
-1/8 < 0.33 < 3/8 < 75% < 1 5/8
This is overdetermined. Without looking at the ratio (except for the order of the sides) the actute angles in a right triangle are complementary so the answer must be:
Answer: A=35°, C=90°, B=55°
We can do it the way they like.
7+18+11 =36
so to get 180 degrees we need to scale the ratio elements by a factor of 5.
7:18:11=35:90:55
A is the smallest. We see C is indeed a right angle and B is complementary to A.
