Simplify (3x+8)(x+1) using a table, the Distributive Property, and the FOIL
Diano4ka-milaya [45]
Foil method:
FOIL stands for
first-multiply the first term in each set of parenthesis
outer-multiply the outer term in each of the perenthesis
inner- multiply the inner term in each of the parenthesis
last- multiply the last term in each of the parenthesis
(3x+8)(x+1)
(3x*x)=3x^2
(3x*1)=3x
8*x=8x
8*1=8
thus we shall have:
3x^2+3x+8x+8
=3x^2+11x+8

Distributive property:

(3x+8)(x+1)
3x(x+1)+8(x+1)
3x^2+3x+8x+8
=3x^2+11x+8

Both methods are efficient, it all depends with the users preference

Can anyone do this for me?! I don’t understand
gayaneshka [121]

Answer:

Step-by-step explanation:

Q no 4 :

4, 8

1, 5

3, 7

2, 6

Q no 5:

(a)

10x + 1 = 12x - 5

1+5= 12x - 10x

2x = 6

x = 6/2

x = 3

(b)

11x - 15 + 5x - 13 = 180 (angles on a straight line)

11x + 5x - 15 - 13  =180

16x - 27 = 180

16x = 180 + 27

16x = 207

x = 207 / 16

x = 12.9375
