Answer:
I know this is really late but if anyone else needs help I hope this will help those people.
Step-by-step explanation: so expand (3x+5) (X-2) first apply FOIL method: (a+b) (c+d)= ac + ad +bc + bd..... a= 3x, b=5, c=x, d= -2. our end product would be 3xx+3x(-2) + 5x + 5(-2).
Then apply minus-plus rules: +(-a)= (-a)...... we would end up with 3xx-3 times 2x + 5x - 5times 2.
next simplify until we end up with 3x^2 - x- 10
Not 100% sure if this is what your looking for but this is my best educated guess from the question asked.
Area of base is Circumference x 
or A = 25 x
A = 78.53981
Volume = Area of Base x Height or V = 78.53981 x 8
V = 628.32 Units
The volume of the cylinder is 628.32 units
Answer:
The answer for this question would be 85 and 17/20 or /20
Step-by-step explanation:
You must first find the LCD of these terms (everything that is separated by the addition signs).
The LCD is 20 because:
2 x 10 = 20
5 x 4 = 20
4 x 5=20
and there is no number lower than 20 that all of these numbers share in their multiplication table.
Now you must multiply every term by the number you used to make its denominator 20. Since 2 x 10 = 20, the new term would be:
60 10/20
Since 5 x 4 = 20, the new term would be:
4 12/20
Since 4 x 5 = 20, the new term would be:
20 15/20
Now we put all the whole numbers and numerators together to get:
60 + 4 + 20 = 84 - whole numbers
10 + 12 + 15 = 37 - numerators
84 37/20 = 85 17/20 or 1717/20
Answer:
78/5
Step-by-step explanation:
1/5 5x + 12 = 18
To find the diagonal of the rectangle we have to use Pythagorean theorem!
Pythagorean theorem is used to find the length of a missing angle such as the hypotenuse or the sides a and b.
Steps to solve:
1. 12 in is the length or the base of the right triangle, and 6 in is the wide or the side a.
2. Now use the formula: a^2+b^2=c^2, and plug in the numbers!
3. 6^2+12^2=c^2, now just solve the squared numbers.
4. 36+144=c^2
5. 180=c^2
6. Find the square root of 180.
And that is you answer!
If helped mark me the brainiest!!
