<span>(3x-4)+(x+3)^2
= 3x - 4 + x^2 + 6x + 9 .........(expand using (a+b)^2 = a^2 + 2ab + b^2)
= x^2 + 9x + 5 ..........(combine like terms and simplify)
hope that helps</span>
Answer:
y = 1/4x or y = 0.25x
Step-by-step explanation:
In this question, we are trying to write an equation with the given points.
To solve this question, we would use the slope formula: y2-y1/x2-x1
Find the slope by plugging in variables:
2-1/8-4
1/4 = m
The slope would be 1/4
Find the y intercept:
To find the y-intercept, you would need to use the slope you've found and one point, and plug it into the slope-intercept equation:
1 = 1/4(4) + b
Solve:
1 = 1/4(4) + b
1 = 1 + b
Subtract 1 from both sides
0 = b
This means that the y-intercept is 0.
Our equation will be: y = 1/4x
So let's say that the second angle is x.
Then we can say that the third angle is 
.
So then we have three angles:
1) 66°
2) x°
3) ()°
So then we can add these together and solve for x by setting it equal to the total degrees left in the triangle after subtracting the known angle:
So now we know that the measure of the second angle is 38°. So then we can use this value to solve for the third angle:
So the values of the angles are:
1) 66°
2) 38°
3) 76°
It is 0.916. this is because it is 11/12
