(picture) Factoring Polynomials: GCF PLEASEE HELP!!!!! a b c d

Mathematics
1 answer:
White raven [17]3 years ago
7 0

Answer:

5x^2 (2y +5)

Step-by-step explanation:

10x^2y+25x^2

LEts write the factors for each term

10x^2y ------> 5*2*x*x*y

25x^2 -------> 5*5*x*x

common factors will be our greatest common factor

5 , x and x  are in common

so GCF is 5*x*x = 5x^2

Now we factor out 5x^2

10x^2y+25x^2

5x^2 (\frac{10x^2y}{5x^2} +\frac{25x^2}{5x^2})

5x^2 ( 2y +5)

The length of a rectangle is 5 inches longer than it is wide. If the perimeter is 38 inches, what are the dimensions of the rect
faust18 [17]

Answer:

shorter side = 7 in

longer side = 12 in

Step-by-step explanation:

Let w = width

then w + 5 = length

The perimeter of the rectangle = 2 widths + 2 lengths.

So, w + w + w + 5 + w + 5 = 38  or 2w +2(w + 5) = 38 are two ways to write the equation to solve the problem.

Now 4w + 10 = 38

4w = 28

w = 7

w + 5 = 7 + 5 = 12

shorter side = 7 in

longer side = 12 in

Check:  7 + 7 + 12 + 12 = 38 = perimeter

11. A line through points (-5, 2) and (2, y) has a slope of 3.<br> Find y.<br> Help
allochka39001 [22]

Answer:

23

Step-by-step explanation:

  • Create an equation to find y:  3 = \frac{y-2}{2-(-5)}
  • Calculate by adding:  3 = \frac{y-2}{7}
  • Multiply both sides of the equation by 7 : 21 = y - 2
  • Move the variable to the left-hand side and change its sign : -y + 21 = -2
  • Calculate and change signs : y = 23

                                                             y = 23
