Answer:
4
Step-by-step explanation:
If you increase the scale factor by 4, the sides become:
L= 2×4 = 8
W= 3×4 = 12
Now to find the new area:
<u>8 × 12</u> = 96cm^2
<u>So, a scale factor of </u><u>4</u> would give the rectangle a scale factor of <u>96</u>.
<u>Hope this helps and have a nice day!</u>
B.The function is decreasing when x<0 and increasing when x>0
Answer:
4
Step-by-step explanation:
25- 9.5 is 15.5 and 4 ×3.75 is 15 you would have still have .5 cents
(2x-15) + 11x = 180
Combine your like terms in get
13x - 15 = 180
Add 15 on both sides
13x - 15 = 180
+15 + 15
13x = 195
Divide each side by 13 and get
x = 15
(a) 14.90 rounded is 15, and 1.25 rounded is 1, so 15-1 is $14.
(b) My estimation will be high because I had to round up on the larger number and round down on the smaller number leaving a larger gap between the answer and the estimation.
(c) 14.90-1.25=13.65, so Pedro has $13.65 left in his wallet. But the difference between the estimation and the answer is 14-13.65=0.35 so its a $0.35 difference between the estimation and the answer for how much would be left in Pedro's wallet.
