You can only add like terms
exg
you can addd
2+4
2x+4x
2x^2+4x^2
2x^3+4x^3
but not
2+4x
2x^2+2x^3
so when adding like terms keep the exponent
4x+2x=6x
4x^3+2x^3=6x^3
(7x^2+4x-7)+(4x^2-6x+4)
get rid of the parenthasees
7x^2+4x-7+4x^2-6x+4
group like terms (x^2 with x^2 x with x, etc)
(7x^2+4x^2)+(4x-6x)+(-7+4)
add like terms
11x^2-2x-3
You already have all you need. Just put in it the slope-intercept form: y=mx+b where m is the slope and b is the y-intercept so
y=7x-4
Given:
In a right triangle at B,
To find:
The length of the sides b and c and angle B.
Explanation:
Using the trigonometric ratio,
Using the trigonometric ratio,
Using the angle sum property,
The angle B becomes,
Final answer:
The values are,
Answer:
x = 15.4
Step-by-step explanation:
Reference angle = 33°
Opposite side reference angle = 10
Adjacent side = x
Therefore, we would apply the trigonometric function, TOA.
Thus:
Tan 33° = Opposite/Adjacent
Tan 33° = 10/x
Multiply both sides by x
x*Tan 33° = 10
Divide both sides by Tan 33°
x = 10/Tan 33°
x = 15.3986496
x = 15.4 (nearest tenth)
That equals <u>.0124031008</u>
