Angles I and L are congruent!
To simplify the square roots, we apply the square root to the number first, followed by the variable. So for 9x^2, we take the square root of 9 (which is 3), then the square root of x^2 (which is x).
The square root of (9x^2) is 3x. The square root of (18y^2) is (3sqrt2)y. Dividing the first term by the second term gives:x / y(sqrt2).If the final answer must be rationalized, it should be x(sqrt2) / 2y.
Answer:
17.94
Step-by-step explanation:
The formula for a problem like this is
P W/2 -W^2
Multiply the perimeter by half of the width and then subtract the width squared.
7.8/2 This would give us 3.9
Then we multiply this by the perimeter
3.9x20.2 This leads us too 78.78
Then we subtract w^2
7.8X7.8 Is equal too 60.84
Then we subtract
78.78-60.84 This leads us too 17.94
Answer:
y = - 2x + 4
Step-by-step explanation:
Assuming you require the equation of the line.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute (- 1, 6) into the partial equation
6 = 2 + c ⇒ c = 6 - 2 = 4
y = - 2x + 4 ← equation of line
