Which is the correct way to evaluate the expression 48 - (29-17)
Nadusha1986 [10]

Answer:

The correct way to evaluate this expression is my following the order of operations PEMDAS

P=Paranthesis

E=Exponents

M/D=multiply/divide

A/S=add/subtract

The first step in 48-(29-17) is to do what's inside the paranthesis

48-12 (29-17=12)

Then you would subtract 48-12

48-12=36

Your final answer is

36

Hope this helps ;)

Given f(x)=4x^3+7x^2-7x-10 factor f(x), given that -1 is a zero
stira [4]
If - 1 is a zero then
(x + 1)
is a factor.

Dividing with this factor using the long division approach, we get the quadratic factor to be,

4 {x}^{2}  + 3x - 10
(see attachment).

We can rewrite the polynomial as
f(x) = (x  + 1)(4 {x}^{2}  + 3x - 10)

We can further factor as

f(x) = (x + 1)(4 {x}^{2}  - 5x + 8x - 10)
That is

f(x) = (x + 1)(x  +  2)(4x - 5)

Use the quadratic formula to determine the exact solutions to the equation.
lawyer [7]

Answer:

x= 2.28

or, x= 0.219

Step-by-step explanation:

2x²-5x+1 =0

a= 2, b= -5 and c= 1

x= (-b <u>+</u> √(b²-4ac))/2a

= (5 <u>+</u> √(25-8))/4

= (5 <u>+</u> √17)/4
