Answer: 4(−a+1)(a−1)
Step-by-step explanation:
Answer:
x = 16°
H = 46°
I = 55°
J = 39°
Step-by-step explanation:
Since the whole figure is 180°
Deduct 180 by the numbers mentioned above in order to find x.
180 - 2 - 9 - 9 = 160
3x + 4x + 3x = 10x
10 x = 160
x = 160 ÷ 10 = 16
Since we know what x is, we can find all the angles in the figure.
Angle at H = 3 x 16 - 2 = 46°
Angle at I = 4 x 16 - 9 = 55°
Angle at J = 3 x 16 - 9 = 39°
Answer:
12 pigs and 20 chickens
Step-by-step explanation:
Chicken = 2 legs
Pig = 4 legs
(15 * 4) + (17 * 2) = 88 NO
(12 * 4) + (20 * 2) = 88 Yes, and 12 + 20 = 32
Answer: 7
Step-by-step explanation: Imagine having 5 chocolate bars and then adding 2, or you could try counting with your fingers. Another method is writing a number line and going plus 2 from five so you can visualize it more.
