NoThe equation is not quadratic in form.<span>The variable part of the first term is not the square of the variable part of the
second term.</span><span>The result of squaring x cubed is x to the 6thpower, not the 9th power.</span><span>x9 (x3)<span>2</span></span>

The given equation, x9 - 5x3 + 6 = 0, is not a quadratic equation because the exponent of the first term is 9 while that of the second term is 3. The square of 3. If we are to square x3, we should only be getting x6 instead of x9. Therefore, the answer is NO.

Can you guys help me with this one?
svet-max [94.6K]
You can factor this by taking out the GCF (greatest common factor).

In the expression, the greatest common factor between the two terms is 5.

Take out 5:

5(2b + 5)

Is it possible to factor 2b + 5 even more?

No. So, your answer is D. 5(2b + 5).

Answer:

-2

Step-by-step explanation:

Let's solve your equation step-by-step.

−(3v+1)+7(6v+6)=−37

Step 1: Simplify both sides of the equation.

−(3v+1)+7(6v+6)=−37

−3v+−1+(7)(6v)+(7)(6)=−37(Distribute)

−3v+−1+42v+42=−37

(−3v+42v)+(−1+42)=−37(Combine Like Terms)

39v+41=−37

39v+41=−37

Step 2: Subtract 41 from both sides.

39v+41−41=−37−41

39v=−78

Step 3: Divide both sides by 39.

39v

39

=

−78

39

v=−2

Answer:

v=−2
