Answer:

x = -11 and -13

Step-by-step explanation:

expanding the equation

x²+24x+144 = 1

x²+24x+143=0

(x+a)(x+b) = 0, where ab = 143 and a+b = 24

11X13 = 243 11+13 = 24

(x+11)(x+13) = 0

x +11 = 0; x = -11

x+ 13 = 0, x = -13

Evaluate the function f(x) = 2x3 - 6x + 1 for f(-2).

erma4kov [3.2K]

Answer:

- 3

Step-by-step explanation:

$f(x) = 2 {x}^{3} - 6x + 1 \\ plugging \: x = - 2 \\ f( - 2) = 2( { - 2})^{3} - 6( - 2)+ 1 \\ = 2 \times ( - 8) + 12 + 1 \\ = - 16 + 13 \\ = - 3 \\ f( - 2) = - 3$

I=prt for t I=105 p=700 and r=0.05

Pachacha [2.7K]

t = 3

Simple interest will be derived by multiplying the principal, the interest rate, and the term.

Interest = Principal x Rate x Term

Interest = 105
Principal = 700
Rate = 0.05
Term = ?

Based on the Simple Interest formula,

term = Interest / principal x rate
term = 105 / (700 x 0.05)
term = 105 / 35
term = 3
