Answer:
( x + 4 ) ( x + 6 )
Step-by-step explanation:
If 4/10 of the population have blood type O+, that means 40% of the population have that blood type. To change a fraction to percent, the easiest way is to make the denominator 100. To do this, multiply the whole fraction by 1 (1/1, 2/2, etc). In this case, multiply by 10/10. 4/10 * 10/10 is equal to 40/100. Then, if you have a denominator of 100, the numerator is the percent. Therefore, 40/100 is 40%.
Law of sines can be used to solve this problem:
(note - let x represent the missing side length.)
1. set up proportion.
sin 90°/25 = sin 55<span>°/x
2. solve.
(x) sin 90</span>° = (25) sin 55<span>°
(x) sin 90 </span>°/sin 90° = (25) sin 55° / sin 90<span>°
</span>
x = 20.4788011072
rounded to nearest tenth = 20.5
Answer:
8x-24
Step-by-step explanation:
We open parenthesis, so we get:
6x-21+2x-3
Then, simplify by adding like terms:
8x-24 is your answer :)
Stay golden :)
Answer:
Step-by-step explanation:
-8 (x - 3y - 9) = distribute the -8 through the parenthesis
-8(x) - 8(-3y) - 8(-9) =
-8x + 24y + 72
this is the distributive property....u are distributing the -8 through the parenthesis...what that means is ur multiplying -8 by everything in the parenthesis....you do this to remove the parenthesis
