Answer:
The correct option is A
Step-by-step explanation:
The expression is
2y3 - 27 + 5y2 + (25 / 5)
Substitute the value of y=2 in the expression:
=2(2)³-27+5(2)²+(25/5)
We know that 2³ means multiply 2 three times
2³= 2*2*2=8
Likewise 2²=2*2=4
=2(8)-27+5(4)+(25/5)
=16-27+20+25/5
Now take the L.C.M which is 5
=80-135+100+25/5
Solve the values in the numerator:
=70/5
=14
Thus the correct option is A....
The answer would be 4.55 Km
Do 650*7=4,550
Then do 4,550/1,000=4.55
Hope this helps!
Is 1/3 of what equal to 25 inches.
But 1/3 of 1 is = to approximately 33 inches.
Answer:
The value of x is 21.
Step-by-step explanation:
Since this is a right angle triangle, you can apply Pythagoras theorem, side² + side² = hypo² :
(x + 3)² + 10² = (x + 5)²
x² + 6x + 9 + 100 = x² + 10x + 25
x² + 6x + 109 - x² - 10x - 25 = 0
-4x + 84 = 0
-4x = -84
4x = 84
x = 84 ÷ 4
x = 21 units
39/69 = 13/23 is in simplest form
First you do 39 divide by 3 = 13 and do 69 divid by 3 = 23
