Simplify polynomial 2x^2+6x-7x+8-3x^2+1

Step-by-step explanation:

To simplify the given polynomial we need to add the like terms. Then we get:

Therefore, we get that the polynomial simplified is:

Which is a trinomial ( A polynomial that has three terms) of degree 2 (Because the highest exponent is 2).

Final answer is .

Step-by-step explanation:

Given polynomial is .

Now we need to simplify the given polynomial so we can begin with combining like terms.

Hence final answer is .

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
