Answer 1

Answer: if the area of a rectangle is width time length, then we have all of the info we need.

the width is 6 less than 3 times the length. let the length be x and put your words into math! 6 less is -6. 3 times a number is 3x, so width=3x-6.

so we have area=l×w which becomes x×(3x-6)=105

solve
$x(3x - 6) = 105 \n 3 {x}^(2) - 6x = 105 \n 3( {x}^(2) - 2x) = 105 \n (1)/(3) * 3( {x }^(2) - 2x) = 105 * (1)/(3) \n {x}^(2) - 2x = 35 \n {x}^(2) - 2x - 35 = 0$
factor and solve!

you will get one positive and one negative. pick the positive since lengths cannot be negative

2x(8+7)-6/2x(9-3) evaluate

Answers

ok so assuming that the 'x' means multiply and not 'x' as in placeolder we do

PEMDAS
parenthaseees
exponents
multipilcation or division
additon or subtraction

parethasees simplify first
(8+7)=15

(9-3)=6

now we have
2x(15)-6/2x(6)
multiply
2x15=30

6/2x6=36/2=18

now we have
30-18
12

answer is 12

2x(8+7)-6/2x(9-3)
2x(15)-6/2x(6)
30x-6/2x(6)
30x-3x(6)
30x-18x
12x
