5x+4=114
5x= 110
X=22
114+ 3(22)-24=156
180-156=24
2y=24
Y=12
Your answer is x² + 2x + 1
Answer: 2 × 3 × 3 or we can also write them as 2 × 32, where 2 and 3 both are prime numbers.
Z=-3 is the correct answer. Use math papa if you need help with the steps on how we got z=-3
<span>it all looks confusing when we try to juggle with all those numbers in the head. The problem can be solved systematically by constructing a contingency table.
</span>role/gender B G total
speaking...... 4 4 8
<span> silent............ 4 8 12
total............. 8 12 20
</span>Probability of a child having a speaking part is therefore
(4+4)/20=8/20=2/5
a. 2/5
