Answer:
53/21 OR 2 11/21
Step-by-step explanation:
1 4/6 + 6/7
Change 1 4/6 into an improper fraction
1 4/6 6x1= 6+4= 10/6
Simplify 10/6 --> 5/3
5/3+ 6/7
find a common denominator (21)
35/21+18/21= 53/21
mixed number form is 2 11/21
Answer:
-29+7i
Step-by-step explanation:
(5+2i)(-3+i)
-15+5i-6i+2i²
i²=-1
Simplify
-17-i
Add c
c=4i(2+3i)
=8i+12i²
=8i-12
-17-i+8i-12
-29+7i
Answer:
22.1 inches
Step-by-step explanation:
The shadow is formed at a specific factor of the original image hence if a 5 feet tall man casts a shadow rhat is 4 1/3 feet long then a telephone pole casts a shadow that is 25.5 feet long must have a length
5 / 4 1/3 = x / 25.5
where x is the length of the pole
5 / 13/3 = x/ 25.5
15/13 = x/25.5
cross multiply
15 * x = 13 * 25.5
Divide both sides by 15
x = 13 * 25.5 / 15
x = 22.1 inches
The telephone pole in inches is 22.1 long
<u>2x²y + 4x²y² - xy²</u> = <u>2xy(x + 2xy - 0.5xy)</u> = x + 2xy - 0.5xy<u>
</u> 2xy 2xy
