Answer:
D
Step-by-step explanation:
Answer: The pizzaria made $20 less on Wednesday than Tuesday.
1/10 of 200 is 20.
if you subtract 20 (the $20 less than Tuesday) from $200 you get $180, which is 9/10 of $200.
[this shows two different ways to find the answer, finding 1/10 or 9/10 of $200.]
So we know that ten percent is e quivanebt to 0.10 multiply that number to 100 and you will get your answer!
Answer:
3w² + 10w +8 (C)
Step-by-step explanation:
A rectangle has a length that is 3 times its width, w, in inches. The width is increased by 2 inches, and the length is increased by 4 inches. Which expression represents the area of the larger rectangle?
First, remember that the length of the first rectangle is 3 * w, or 3w.
Now, onto the second rectangle.
The width is increased by 2, so it becomes w + 2
The length is increased by 4, so it becomes 3w +4.
Area is length times width, so the area is
(w + 2)(3w + 4)
Simplify.
3w*w + 4*w + 2*3w + 2*4 =
3w² + 4w + 6w +8
3w² + 10w + 8, or C
81
(-9)(-9) is 81
Multiplying two negatives gives a positive
