Answer:
x = 70, y = 90
Step-by-step explanation:
A straight line is equal to 180 degrees, so if 180 is split between 110 and x. Subtract the 110 to get the rest. 180-110 = 70.
All sides in a quadrilateral add up to 360 degrees, add all of the remaining angles (112+88+70) to get 270. 360-270 = 90 degrees. Y is 90 degrees.
A polynomial is a perfect square trinomial if in form
a^2x^2-2ab+b^2
look at each
we can eliminate A and B since we have -b^2 not +b^2
look at the rest
C. 5^2b-3*5*b+3^2
nope
D. 4^2x^2-2*4*3x+3^3
yes
answe is D (factors to (4x-9)^2)
I'm guessing you mean magazines as in bullets. Well, if he paid $412 dollars for two, and each were sold as a multiple of 43. Then each bullet was $4.79.
You find this by dividing 412 by 2 which gives you $206.
Now divide that by 43. Which is $4.79 (.ea) bullet.
2 * 2 and 3/4.
2 and 3/4 = (4*2 + 3) / 4 = (8 + 3) / 4 = 11 / 4
2 * 11/4 = 22 / 4 = 5 and 2/4
= 5 and 2/4 or 5 and 1/2 or 5.5
Hope this helps.
Your answer is 48 minutes because you divide 6.72 by 0.14
