Four bought a book at $6
4 x $6 = $24
8 x $x = $8x
Expression
$24 + $8x
Answer:
5 and 7.
Step-by-step explanation:
Hey! So to start you need to create an algebraic expression. You can express this problem through the following equation:
*Note: if x is an odd integer, x + 2 is the next consecutive odd integer.
Expanding, you get:
And moving the 35 to the other side, you get a simple quadratic.
Solving by factoring:
This means two possible solutions for the smaller consecutive number are -7 and 5. However the question asks for two positive odd integers, so one of the numbers must be 5. The next will be 7(as its x + 2).
3x+10=40 , 40-10= 30 , 30/3 = 10. x=10
Hey there!
I want you to think of radicals as like terms. In order to be able to combine like terms, you need the same <em>base </em>and <em>exponent. </em>
<em>For example, </em>
3x^2-y^2 <== same exponent but not same variable
3x^2-x^2 <=== could be combined because exponent (^2) and variable (x) are the same
So, for this question, you're looking for a radical that has 5 under the radical sign and 3 above the radical sign.
"B" is the right answer, because is ∛ and in the radical it has a √5.
I hope this helps!

The area is 113.1m If you want to double check go on google and look up surface area of a sphere. A calculator will come up. Hope this helped.
