Answer:

Step-by-step explanation:

Factoring an expression is the process of undoing the multiplication.

Assume you have a function f(x):

f(x)=x^2+2x-48

This can be factored:

f(x)=(x+8)(x-6)

Using multiplication and the distributive property, you arrive back to:

f(x)=x^2+2x-48

Then you can see clearly that all we've done is reverse the multiplication.

natima [27]

Hey there!

6n^2 - 15

= 6(5)^2 - 15

= 6(5^2) - 15

= 6(5 * 5) - 15

= 6(25) - 15

= 150 - 15

= 135


Therefore, your answer is: 135


Good luck on your assignment & enjoy your day!

Answer:

  (d)  A = 18 units²

Step-by-step explanation:

Line CE can be considered to be the base of two triangles. It is 6 units long. The upper triangle is 4 units high, and the lower triangle is 2 units high. The formula for the area of a triangle is ...

  A = 1/2bh

Then the sum of the areas of the two triangles is ...

  A = 1/2(6)(4) +1/2(6)(2) = 12 +6 = 18

The area of the polygon is 18 square units.
