Sense we know the values of a and b all we need to do is fill them in the problem and solve it
So once you fill them in it would give you -4+(4•-3)
Then you would simplify the parentheses
-4+(-12)
After wards you would add these two numbers together and since they are negative it would appear for the number to be bigger even though it is getter quite smaller
So the answer to this expression would be
= -16

Answer:

-16

Step-by-step explanation:

-a +4b

By putting the value a = 4 and b = -3

Answer:

{ x^2+3x-4}

Step-by-step explanation:

Factor top and bottom.

The numerator is a difference of two squares, and the denominator is a quadratic.

\frac{ {9x}^{2} - {(x}^{2} - 4)^{2} }{4 + 3x - {x}^{2} }

= \frac{ (3x+x^2-4)(3x-x^2+4) }{(1+x)(4-x)}

= \frac{ (x-1)(x+4) (1+x)(4-x) }{(1+x)(4-x)}

If x does not equal -1 and does not equal 4, we can cancel the common factors in italics to give

= { (x-1)(x+4)}

= { x^2+3x-4}

Three friends got the prize money worth ​$231,000
Degger [83]
There are three unknowns in this problem. First, let's assign variables for these unknowns.

Let
x be the amount received by the first friend
y be the amount received by the second friend
z be the amount received by the third friend

Next, we formulate equations for the relationships

x = 4z
z = 4y
x + y + z = <span>$231,000

Solving simultaneously,

4(4y) + y + 4y = </span><span>$231,000
21y = </span><span>$231,000
y = $11,000
z = 4($11,000) = $44,000
x = 4($44,000) = $176,000</span>
