The answer is 2.
3/x = 18/12
3/2 = 1 1/2
18/12= 1 1/2
The answer is 2.
Answer:
3x^2 + 3xy/2 - 7xy^2/2
Step-by-step explanation:
So we know the perimeter is 20x^2 + xy - 7y^2,
To find any perimeter you need 2l + 2w = P so,
One of the sides is 7x^2 - xy
First plug in the values,
2(7x^2-xy) + 2w = 20x^2 + xy - 7y^2
Multiply,
14x^2-2xy + 2w = 20x^2 + xy - 7y^2
Subtract,
14x^2 - 2xy - 14x^2 + 2xy + 2w = 20x^2 + xy - 7y^2 - 14x^2 + 2xy
2w = 6x^2 + 3xy - 7y^2
w = 3x^2 + 3xy/2 - 7xy^2/2
Okay first if you want to find the angle of 4, you have to complete the first triangle's angles.
So since the 2 angles that are in the triangle are 25° & 52<span>°
Then you add them together and get 77</span><span>°
Next you subtract 77</span>° from 180°, so you should get 103<span>° for angle 3
Finally you subtract 103</span>° from 180° to complete line segment ←PAL
Final Answer: 77<span>°</span>
299.65. You add thursday, friday, and saturday to 109.30.
