First you would simplify the equation <span>(7x²+2x+5)+(3x²-8x-10) lets start with the first part
</span><span>(7x²+2x+5)
</span>7x² + 2x which = 49x + 2x which also = 51x Then you add the last part (+5)
51x + 5
Now you simplify the last part.
<span>(3x²-8x-10)
</span>3x²-8x which=9x - 8x which also = 1x or simply x Then add the last part (-10) Which you'll get x-10
51x + 5) + (x - 10) = 52x -5
so your answer is 52x - 5
Use the formula: A=2(3.14)rh+2(3.14)r^2
A=2(3.14)(6)(7)+2(3.14)6^2
A=490.09 so the answer rounded would be 490.1
No you should not do that.
Answer:
a or b
Step-by-step explanation:
it should be p≥18
greater then or equal to 18. because if you have 18, you can get the group rate and I'd you have more than 18 you can also get the group rate.
20% because 10% of 40 is 4 so 4+4=8 then that is 10%+10% so 20% will be your answer. :)
