Mathematics

(4x - 2) x (12x +42)  (I distributed the 6 over the 2x and the 7)

Using the FOIL method
First terms  (in each parenthesis) 4x  times 12 x = 48x²
Outer terms  4x times 42 = 168x
Inner terms    -2  times 12 x = -24x
Last terms -2 times 42 = -84

So we have 48x² + 168x + 168x - 24x -84
Finally combine like terms:

48x² + 144x - 84    There's your quadratic expression

(This is literally 7th grade math dude should be easy for most of you)
Korolek [52]

Answer:

a. no b. 40.05

Step-by-step explanation:

a. to figure out the number of goals per game you have to divide the total amount of goals by the number of games:

last season: 41 ÷ 15 = 2.73

this season: 24 ÷ 9 = 2.67

as you can see the answer to the last season equation is higher than the this season meaning the player scored more goals last season.

b. we already know that the amount of games the player won each game (all of them supposedly being exactly even) is 2.67. so what we have to do is multiply it by 15 the supposed number of games the player is playing this season to get the total number of goals they will get for the entire season:

2.67 x 15 = 40.05 = the prediction of the total goals of the player

Answer:

Substitute -8 as x into the equation.

h(-8)=-2(-8+5)^2+4

h(-8)=-2(-3)^2+4

h(-8)=-2(9)+4

Take the coordinates of the two points.

(0,8) and (7,3)

Formula:

√(x₁ - x₂)² + (y₁ - y₂)²

Substitute:

√(0 - 7)² + (8 - 3)²

√(-7)² + (5)²

√(49) + (25)

√(74) ≈ 8.6
