Answer:
221
Step-by-step explanation:
Try grouping in paires
4x^3 + 28x^2 + 7x + 49
= 4x^2(x + 7) + 7(x + 7) - note that (x + 7) is common to the 2 parts, so
= (4x^2 + 7)(x + 7)
Answer: 1/3 =0.33
Step-by-step explanation:
just substitute the values of x and y into the expression to get
4(2)+1 /3(3)^2
=8+1 /3×9
=9/27
=1/3
=0.33
The value of 
for x = 5 is 0.06
<h3>How to solve the probability?</h3>
The expression is given as:
This means that:
n = 10
p = 0.75
The probability is then calculated as
This gives
Evaluate the combination expression
Evaluate
P(5)= 0.06
Hence, the value of for x = 5 is 0.06
