Mr. Kelly finally bought his DREAM HOUSE...a real life house made of LEGO's. He wants to find out how many LEGO's went into building the house. He knows that he house is 25 fee long. 20 feet wide and about 19 feet tall. He also knows that the dimensions for each LEGO is .15 feet by .1 feet. How many LEGO's did it take to make the outside of the house? (Assume the floor is NOT made of LEGO's, so do not include it in your calculations)

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
