Answer:
9(5e-3f)
Step-by-step explanation:
so, to start, you want to see what they have in common. the variables are not the same, so you cannot take a variable out; however, 45 and 27 have something in common. they can both be divided by 9! (this is a skill you will have to practice). so, after recognizing this, you can divide both numbers by 9, and you would have 5e-3f. however, we cannot just change that because that is not equal to 45e-27f. so, we make sure we include what we did. because we divided by nine, we are going to put the greatest common factor outside of the numbers after we put them in parentheses. 9(5e-3f). we do this because multiplication is the opposite of division, and so this just shows that if we use the distributive property, it would multiply back out to 45e-27f. I hope this helps!
Because 45 is half of 90, 5x=90. 5 times 18 is 90 so x is 18.
The distance formula is sqrt((x1-x2)^2 + (y1-y2)^2), therefore (3-(-6))^2 = 9^2 and (5 -(-6))^2 = 11^2 so 121 + 81 = sqrt(202), this converted to decimal is ~14.21, so D.
Well if 1 is 20 square inches then times 20 X 30 which equals 600. So the area is 600 square inches.
