Answer:
4 x 9 = 36
14 x 5 = 70
70 + 36 = 106 sq cm
(Not really sure if this is correct but hope it helps).
Answer:
Step-by-step explanation:
We are given that:
And we want to find the value of cos(A) and sin(A).
Recall that tangent is the ratio of the opposite side to the adjacent side.
Therefore, the opposite side measures 2<em>ab</em>, and the adjacent side measures <em>a</em>² - <em>b</em>².
Using the Pythagorean Theorem, solve for the hypotenuse:
Thus, our hypotenuse is given by <em>a</em>² + <em>b</em>².
Cosine is the ratio between the adjacent side and the hypotenuse. Thus:
And sine is the ratio between the opposite side and the hypotenuse. Thus:
In conclusion:

EXPLANATION
The given equation is:
Comparing this to
we have a=2, b=-5, c=1
The quadratic formula is given by
We substitute the values to get,

Hm it’s false , your welcome have a great day!
The answer is C.
It’s a solid line so you know it has to be an inequality with a “or equal to” sign. Which leaves you with B or C. Find a point that isn’t on the line to test, use origin to make it simple. Plug it in for the x and y values. So 0 is greater than it equal to 0 - 3 which is -3. 0 is greater than -3 which means C is correct.
