That’s grammatically incorrect
Answer:
Step-by-step explanation:
<u>8.</u> The angles are equal, so:
(2x+2) = (3x - 63)
-x = -61
x = 61
Angle (2x+2) is 124°
Angle (3x-63) is 120°
<u>9.</u> The sum of all angles in a triangle is 180°.
The sum of the two unknown angles is 90° [180° - 90° from the right angle°]
(8x+2) + (9x+3) = 90°
17x + 5 = 90°
17x = 85°
x = 5
The two angles are:
(8x+2) = 42°
(9x+3) = 48°
After 2 hours, there are 12 bacteria present.
Answer:
<h2>D. Quadrant III</h2>
Step-by-step explanation:
Quadrant in coordinate geometry is divided into four parts which is called Quadrants.
Quadrants I (x, y)
Quadrants II (-x, y)
Quadrants III (-x, -y)
Quadrants IV (x, -y)
so W(-3, -9) both are negatives so its lie on Quadrants III
