Please help with a math problem :/ Please show steps... x^2 -13x = -36

Mathematics

Marianna [84]3 years ago
4 0
X^2 -  13 x = -36 
add 36 to both sides

x^2 - 13x +36 = 0
figure out the factor
(x-4)(x-9) = 0
so (x-4) or (x-9) equals 0
so solution is
x-4=0 add 4 to both sides and get x = 4
x-9=0 add 9 to both sides and get x=9
x={ 4, 9}

17. You have $850 to buy new carpet for the game room. The dimensions of the game
gregori [183]

Answer:

Cost of new carpet per square foot should be less than or equal to $3.54.

Step-by-step explanation:

Given:

Money have to buy carpet = \$850

dimension of game room is 20 feet by 12 feet

So we can say length l = 20 feet

and width w = 12 feet

let x be the cost per square foot for new carpet.

Assuming game room to be rectangular in shape we will find the area of it.

Area of room = length \ l \times width \ w = 20 ft\times 12 ft = 240 \ ft^2

Total area \times cost per square feet ≤ Total money we have

Hence,

240 \ ft^2 \times x \leq \$850\\\\x\leq \frac{\$850}{240 \ ft^2}\\\\x\leq \$3.54 \ per \ ft^2

Hence Cost of new carpet per square foot should be less than or equal to $3.54.
