closed circle on number 3 and draw the line to the right
Answer:
w = -7/6 u
Step-by-step explanation:
The independent variable is in the equation, we solve for the dependent variable
So we solve for w
4u + 8w = -3u + 2w
Subtract 2w from each side
4u + 8w-2w = -3u + 2w-2w
4u+6w = -3u
Subtract 4u from each side
6w = -3u-4u
6w = -7u
Divide by 6
6w/6 = -7u/6
w = -7/6 u
Answer:
![n = 68](https://tex.z-dn.net/?f=n%20%3D%2068)
Step-by-step explanation:
To have a complete value of angle, it must always go up to 180°
<u>Therefore:</u>
We already know one value and it is 44°
180° - 44° = 136°
<u>Then since we have to n values left, we divide 136° by 2 to get the result:</u>
136° / 2 = 68° each
<u>Check our work:</u>
<u></u>
44° + 68° + 68°
=> 180°
Answer:
(x - 3) • (x^2 - 4x - 7)
Step-by-step explanation:
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-4x-7
The first term is, x2 its coefficient is 1 .
The middle term is, -4x its coefficient is -4 .
The last term, "the constant", is -7
Step-1 : Multiply the coefficient of the first term by the constant 1 • -7 = -7
Step-2 : Find two factors of -7 whose sum equals the coefficient of the middle term, which is -4 .
-7 + 1 = -6
-1 + 7 = 6
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
(x - 3) • (x2 - 4x - 7)
