If a=3, b=-5 fond the value of (2a+3b) (4a sq- 6ab+9b square)​

Mathematics

snow_lady [41]3 years ago
4 0

Step-by-step explanation:

(2a+3b)(4a²-6ab+9b²

(2a+3b){(2a)²-2a×3b+(3b)²}

Because (a³+b³)=(a+b)(a²-ab+b²)

Therefore,

(2a+3b){(2a)²-2a×3b+(3b)²}

=(2a)³+(3b)³

By substituting the values , we get

  • (2a)³+(3b)³
  • (2×3)³+(3×(-5))³
  • 6³+(-15)³
  • 216+(-3375)
  • 216-3375
  • -3159

What is (w-4/9)(-2/3)=-4/5
pshichka [43]
<span>(-2/3)*(w-(4/9)) = -4/3 // + -4/3

(-2/3)*(w-(4/9))-(-4/3) = 0

(-2/3)*(w-4/9)+4/3 = 0

4/3-2/3*(w-4/9) = 0

(-2/3*3*(w-4/9))/3+4/3 = 0

4-2/3*3*(w-4/9) = 0

44/9-2*w = 0

(44/9-2*w)/3 = 0

(44/9-2*w)/3 = 0 // * 3

44/9-2*w = 0

44/9-2*w = 0 // - 44/9

-2*w = -44/9 // : -2

w = -44/9/(-2)

w = 22/9

w = 22/9</span>

Plz do have mercy and help me
Nikitich [7]
I have mercy:

8x and 9x+5 (the angles) form a right angle so 8x+9x+5=90 which means x is 5 and plugging it back into the angles 8x we get 40 sinceBHR and angle 8x are vertical angles they are equal to each other and so it's equal to 40
