Answer:

2(x + 15)(x-1)

Step-by-step explanation:

In order to factor, we take out common terms.

  1. 6x^{2}  + 28x -10
  2. The biggest common term we can factor out is 2:
  3. 2(3x^{2} +14-5)
  4. Now we factor the area in parentheses into 2 binomials. To do this we need 2 numbers that multiply to be -15 and add to be 14. Theses numbers are 15 and -1.
  5. 2(x + 15)(x-1)

Answer:

Circle 1=6x+2y

Rectangle 4 = 3x+y

Circle 4 = 5x

Step-by-step explanation:

4x+3y and 2x-y can be added to find result for the circle.

Let C1 represent circle 1

4x+3y+2x-y=C1\\

Combining\:like\:terms\\

4x+2x+3y-y=C1

6x+2y=C1

So, The result is: C1=6x+2y

Now, We need to solve:

Let R1 represent rectangle 4

x+4y + R1 = 4x+5y

R1=4x+5y-(x+4y)

R1=4x+5y-x-4y

R1=4x-x+5y-4y

R1=3x+y

So, Solving x+4y + R1 = 4x+5y, We get R1 = 3x+y

Now, We need to solve the equation:

Let C4= Circle 4

2x-y+3x+y=C4

Combining the like terms

2x+3x-y+y=C4

5x=C4

So, Solving 2x-y+3x+y=C4 we get C4 = 5x

Find b given that p(b,2) is equidistant from a(5,4) and b(2,5)
Oksana_A [137]
Hello : 
PA = PB  or  PA² = PB²
(5-b)²+(4-2)² = (2-b)² + (5-2)²
(5-b)²+4 = (2-b)² + 9
25 -10b +b² + 4  =  4 -4b+b² +9
-6b = -16 
b = 8/3
