x^2-4^2
Answer:
10x+13y
Step-by-step explanation:
remove parentheses:
2x+3y+8x+10y
add like-terms:
2x+8x+3y+10y
add numbers with the same variables/elements
10x+3y+10y-->10x+13y
hope this helps
It is wrong because the equation is missing parentheses around the sum
When it says "the quantity of..." it always means parentheses. The correct equation is 2(3x+4)
Find area of room
aera=legnth wtimes width
in a square, legnth=width
aera=legnth^2
legnth=14 feet
convert o inches
14*12=168 inches
area=168^2=28224 square inches
how many tiles will cover all of floor?
aka
how many 192 in^2 is at least 28224 (at least, because we need to cover the whole floor without gaps)
192x<u>></u>28224
divide both sides by 192
x<u>></u>147
147 is the number of tiles we need
