151.54 is the answer
The 54 is underlined hence they repeat(use a calculator and you'll see).
Answer:

Answer:
£6911 is the smallest amount Cynthia should invest to get £8000 after three years
Step-by-step explanation:
lets Assume that amount needs to invested for three years = £ x Rate of Interest = R = 5% per year Duration in years = n = 3 year
Amount expected after three years when compounded annually = A = £8000 Formula for Amount of compound interest annually is a follows A = P( 1 + R/100)^n In our case Principal P = x , Amount A = 8000 , R = 5% and n = 3( since compounded annually). On substituting these values in above formula we get 8000 = x ( 1 + 5/100)^3 ⇒8000 = x ( 105/100)^3 ⇒8000 = x ( 21/20 )^3 ⇒(8000 × 20 × 20 × 20)/(21×21×21) = x ⇒x = 6910.70≈6911
Hence £6911 is the smallest amount Cynthia should invest to get £8000 after three years
In this question, you would be simplifying.
Simplify:
(-x³- x) + (6x² + 6x - 7)
-x³- x + 6x² + 6x - 7
-x³ + 6x² + 5x - 7
You can't simplify any further, so your answer would be:
-x³ + 6x² + 5x - 7
Answer:
-x^3 + 6x^2 + 5x - 7
