Answer: A
You’re basically adding m - 2 nine times
So it’s 9m - 18
Or 9m - 9(2)
We have to solve this quadratic equation for n to get <em>which figure has 56 blocks</em>.
For middle term factorization, we need <em>two numbers that multiplied gives us -56 and added gives us 1 (coefficient of n).</em>
<em>Such two numbers are </em><em>8</em><em> and </em><em>-7</em><em>. We can now write,</em>
<em></em>
<u><em>"There is no negative figure number possible, so we disregard -8"</em></u>
Our answer is 7.
ANSWER: The 7th figure has 56 blocks.
This is equal to...
We want "x" so we need to isolate it using laws of exponents...
because
because
x = 4
