Solve the equation 3p (3p - 8) - 8 = 9p ( p - 3 + 4

pentagon [3]

Answer:

$p= \frac{-8}{33}$

Explanation:

Given:

$3p (3p - 8) - 8 = 9p ( p - 3 + 4)$

To Find:

Value of p=?

Solution:

Before solving this equation, we will use the method of BODMAS which states that we first solve the Bracket then Off then Division then Multiplier then addition and at last subtraction.

Now we will solve the both right and left hand side of the equation

$3p (3p - 8) - 8 = 9p ( p - 3 + 4)$

$9p^2-24p-8=9p^2+9p$

Gruoping the like terms we get,

$9p^2-9p^2-24p-9p=8$

After solving the both right hand and left hand side of the equation

$-33p=8$

And we get the value of p as

$p= \frac{-8}{33}$

7 - 7(-8 + x) = -14 + 4x How do you solve for x

Lelu [443]

First thing you need to do is distributive property and that will give you
7-56-7x=-14+4x then combine like terms which will then give you
-49-7x=-14+4x Next get your letters on the left do that by subtracting 4x which will give you -49-11x=-14. After that you will add 49 to both sides which will give you
-11x= 35. Divide by -11 to get x=3.18

Answer:

AB = 12 cm

Step-by-step explanation:

AB/BC = XY/BY

From the above question:

AB = ??

BC = 9cm

XY = 4cm

BY = 3 cm

AB/9 = 4/3

Cross Multiply

AB × 3 = 9 × 4

AB = 9 × 4/3

AB = 12 cm

Therefore, Length AB = 12cm
