What is (x+7)(x-4) simplified
fomenos
(x + 7) (x - 4)

First, apply the FOIL method (a + b) (c + d) = ac + ad + bc + bd / Your problem should look like: x^{2} - 4x + 7x - 28
Second, gather the like terms. / Your problem should look like: x^{2} + (-4x + 7x) - 28
Third, simplify. / Your problem should look like: x^{2} + 3x - 28

HELP??????????????????????????/???????????????????????????????????????????????????/??????????A fruit company delivers its fruit
Sphinxa [80]

Answer:

small: 6.25

large: 18.25

Step-by-step explanation:

Set the large boxes as x and the small boxes as y (The weight is the constant).

3x+5y=86

6x+2y=122

Now just solve the systems of equations using either substitution or elimination.

-6x-10y=-172 multiply the whole equation by -2 to eliminate

6x+2y=122, add the equations

-8y=-50

y= 6.25

Plug in y either equation:

3x+5(6.25)=86

3x=86-31.25

3x=54.75

x=18.25

Each small box weighs 6.25 kilograms, each large box weighs 18.25 kilograms, to check plug in the values to the other equation to see if they add up correctly.
