Answer:

Step-by-step explanation:

-2x- 4 + 5x = 8

Collect like terms

-2x + 5x = 8 +4( when a variable crosses over equality sign it becomes either negative or positive depending on the sign)

3x = 12

Divide via by coefficient of x

X = 12/3

= 4

X=7. The two segments on the bottom as well as on the diagonal are the same length. This shows that the entire triangle and the inner triangle on the right are similar. So if we call the length of the bottom 2y, then 84/2y=6x/y. Solving this we get 84=12x, and so x=7

Answer:

$\large\boxed{\boxed{\underline{\underline{\maltese{\pink{\pmb{\sf{\: SOLUTION: \: \: \: \: (3x + 4)^{2}}}}}}}}}$

Step-by-step explanation:

The given statement is;: 'I think of a number, multiply it by 3, add 4 & square the result.'

At first, let's take the unknown number as 'x' . (asked in the question).

So, the number we think about = x

Now, we need to multiply it by 3. So,

3 * x = 3x

In the next part, we need to add 4 to it so,

3x + 4

Now, by squaring the result, we'll get the expression as,

(3x + 4)²
