Answer:

x = - 4 , x = - 2

Step-by-step explanation:

x² + 6x + 8 = 0

consider the factors of the constant term (+ 8) which sum to give the coefficient of the x- term (+ 6)

the factors are + 4 and + 2 , since

4 × 2 = 8 and 4 + 2 = 6 , then

(x + 4)(x + 2) = 0 ← in factored form

equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x + 2 = 0 ⇒ x = - 2

Brian invests £1500 into his bank account. He receives 2% per year simple interest. How much
Sauron [17]

Answer:

Step-by-step explanation:

Simple interest is given as

S.I = PRT/100

Where

S.I is simple interest

R is rate in %

P is the principal

And T is time in years

So, given that

Principal (P)=£1500

Rate(R) =2%

Time(T)= 3years

Then, we are asked to find amount after 3years

S.I=PRT/100

S.I=1500×2×3/100

S.I= £90

This is the interest Brian will receive

So, the money will amount to

Amount=Principal + interest

Amount = 1500+90

Amount = £1590.

So Brian will have £1590 after 3years

Unsure how your teacher wants the table to be filled out, but the solution is about 1.62.

x = 1.75, f(x) =1.0625, g(x) =.75 \\  \\ 
x = 1.64, f(x) =.6896, g(x) =.64 \\  \\ 
x = 1.63, f(x) =.6569, g(x) =.63 \\  \\ 
x = 1.62, f(x) =.6244, g(x) = .62 \\  \\ 
x = 1.61, f(x) = .5921, g(x) = .61
