Answer: This is a quadratic equation in x and can be solved using the quadratic formula: x = (-b +_ (b^2 - 4 ac)^1/2) / (2 * a)
or (-7 +- (49 - (4 * 2 * 6))^1/2) / (2 * 2) where a=2, b=7, and c=6
and x = (-7 +- (49 - 48)^1/2) / 4 = (-7 +- 1) / 4
giving x = -8/4 and -6/4 or -2 and =3/2
The problem simplified is 36√ 2abc
(34×2)+(72×2)
34×2=68
72×2=144
68+144=212
the dimension of the sewing room is 212 square feet
Answer:
x =12.82
Step-by-step explanation:
1/2(x-6.5) = 3.16
Multiply each side by 2
1/2(x-6.5) *2 = 3.16 *2
(x-6.5) = 6.32
Add 6.5 to each side
(x-6.5+6.5) = 6.32+ 6.5
x =12.82
75x0.2=$15 saving as 20% of 75 is $15
