X^2=12x-27 solve by factoring

Mathematics
1 answer:
Alex Ar [27]3 years ago
3 0

Answer:

X=3 or X=9

Step-by-step explanation:

Step 1: Subtract 12x-27 from both sides.

x2−(12x−27)=12x−27−(12x−27)

x2−12x+27=0

2: Factor left side of equation.

(x−3)(x−9)=0

Step 3: Set factors equal to 0.

x−3=0 or x−9=0

x=3 or x=9

babymother [125]

Answer:

Speed of Carol is 78 mph and that of Steve is 84 mph.

Step-by-step explanation:

Let the speed of Carol is x mph and that of Steve is (x + 6) mph.

If they move towards each other with that speed, then the resultant speed will be (x + x + 6) = (2x + 6) mph

With this resultant speed, they cover 405 miles in 2.5 hours.

So, 2x + 6 = \frac{405}{2.5} = 162

⇒ 2x = 156

⇒ x = 78 mph

So, speed of Carol is 78 mph and that of Steve is (78 + 6) = 84 mph. (Answer)

svlad2 [7]

Answer:

x = 4

Step-by-step explanation:

Since the rectangles are similar, use a ratio.

15/6 = 10/x

or

6/15 = x/10

I will use 15/6 = 10/x to solve this problem, but both ratios should work to solve this problem.

15/6 = 10/x

Cross Multiply:

6(10) = 15x

Solve:

60 = 15x

x = 4
