Answer: The answer is 
Step-by-step explanation: Given expression is as follows

We are to write the above expression "E" as a product of two binomials and a monomial.
A monomial is an expression with a single term and a binomial is an expression with two terms.
So, let us start as follows -

Here,

Thus, the required factorisation is

F(-1)= 4*7(-1) = 4*-7 = -28
F(2)= 4*7(2) = 4*14 = 56
Answer:
63%
Step-by-step explanation:
Given the following :
Average cholesterol level or mean (m) = 194
Standard deviation (sd) = 15
what percentage of children have a cholesterol level lower than 199?
P(X < 199)
Assume a normal distribution :
Find the z-score :
Z = (score - mean) / standard deviation
Score = 199
Z = (199 - 194) / 15
Z = 5 / 15
Z - score = 0.3333
P(Z < 0.33) :
Using the z - table ; 0.33 = 0.6293
P(Z < 0.33) = 0.6293
0.6293 * 100% = 62.93%
= 63% (nearest whole percent)
