I’m terms of 12 in is the correct answer.
Answer:
The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.
Step-by-step explanation:
This question is solved using a system of equations.
I am going to say that:
x i the height of a large block.
y is the height of a small block.
Taylor uses 4 large blocks and 2 small blocks to make a tower 63.8 inches tall.
This means that:
Simplifying by 2:
So
Natsumi uses 9 large blocks and 4 small blocks to make a tower 139.8 inches tall.
This means that:
Since
The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.
A perfect square trinomial is found in the expression where both the leading coefficients and the constant are both perfect squares. That only is the case with the third choice above. 16 is a perfect square of 4 times 4, and 9 is a perfect square of 3 times 3. We need to set it up into its perfect square factors and FOIL to make sure, so let's do that. Not only is 16 a perfect square in that first term, but so is x-squared. Not only is 9 a perfect square in the third term, but so is y-squared. So our factors will look like this:
(4x + 3y)(4x + 3y). FOIL that out to see that it does in fact give you back the polynomial that is the third choice down.
