this doesn't make sense im also in middle school sooo...
Answer:
9^20
Step-by-step explanation:
When the exponents are multiply by an exponent, you multiply the exponent in this case the exponents are 4 and 5 so 4(5)=20.
In order to factorate the trinomial, let's first find its roots using the quadratic formula:
![\begin{gathered} b^2-4ac=12^2-4\cdot4\cdot9=144-144=0 \\ x_1=x_2=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}=\frac{-12+0}{2\cdot4}=-\frac{12}{8}=-\frac{3}{2} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20b%5E2-4ac%3D12%5E2-4%5Ccdot4%5Ccdot9%3D144-144%3D0%20%5C%5C%20x_1%3Dx_2%3D%5Cfrac%7B-b%5Cpm%5Csqrt%5B%5D%7Bb%5E2-4ac%7D%7D%7B2a%7D%3D%5Cfrac%7B-12%2B0%7D%7B2%5Ccdot4%7D%3D-%5Cfrac%7B12%7D%7B8%7D%3D-%5Cfrac%7B3%7D%7B2%7D%20%5Cend%7Bgathered%7D)
Now we can write the trinomial in the form:
So we have that:
So 2x + 3 is a factor of the trinomial, therefore the answer is D.
Answer:
1.4000
2.5.551
3.6.8
4.10.00
5.4
Step-by-step explanation:
1 4066 as an example start from the end a 5 or more it turns to a zero and the one next to it
so in this case we now have 4100 but since it isn't 5 or more we make it a zero and move on so now we have 4000
sorry if I am wrong I am also an idiot so hopefully this helps for the future :)
