Answer:
(3x+7y)(3x−7y)
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) where a=3x and b=7y
Umm if you need more details just ask.
Hope this helps .-.
Answer: $2295.05
Step-by-step explanation: I don't know how to explain, SORRY!
Given =
∠lkm = 7x - 5
∠nkm = 3x +9
find = value of∠ lkm.
To proof - let us assume that we takeapoint say n and draw a line nk.
nk is angle bisector it divided angle in two equal parts.
( as shown in the diagram given below)
thus we have
∠lkm = ∠lkn + ∠nkm
7x-5 = 3x+9 +3x +9
x = 23
thus the value of∠ lkm
∠lkm = 7x-5
(put the value of x)
thus
∠lkm = 7×23 - 5
∠lkm = 156°
Answer:
it's the first choice: 2x^3 + 5x^2 - x - 6.
Step-by-step explanation:
(f•g)(x)
= f(x) * g(x)
= (x + 2)(2x^2 + x - 3)
= 2x^3 + x^2 - 3x + 4x^2 + 2x - 6
= 2x^3 + 5x^2 - x - 6.
Ok all you need to do is add the decimals together and regroup like regular addition put the decimals on top of each other boom
