Answer: y=3x^2−3x
Step-by-step explanation:
Sorry if wrong
1.3 is the nearest tenth for <span>1.34615384</span>
C = 180 - (22 + 105) = 180 - 127 = 53 degrees
Area of triangle = 1/2 ab sin C
But a / sin A = b / sin B or a = b sin A / sin B = (14 x sin 22) / sin 105 = 5.429
Therefore, Area of triangle = 1/2 x 5.429 x 14 x sin 53 = 30.4 units^2
Answer:
179/180
Step-by-step explanation:
<em><u>Step One</u></em>
Find the prime factors of 18 and 20
18:3*3*2
20: 2 * 2 * 5
<em><u>Step Two</u></em>
You need two 2s two 3s and one 5 for the common denominator
The common denominator is 2 * 2 * 3 * 3 * 5 = 180
<em><u>Step Three</u></em>
Put the two fractions over 180


179/180
Answer:
3x
Step-by-step explanation:
2y + 1 + x + ? = 2y + 1 + 4x
Subtract 2y from each side
2y -2y+ 1 + x + ? = 2y-2y + 1 + 4x
1 + x + ? = 1 + 4x
Subtract 1 from each side
1 -1+ x + ? = 1 -1+ 4x
x + ? = 4x
Subtract x from each side
x-x+? = 4x-x
? = 3x
