Answer:
l = 10.5 cm and A = 21 cm2
Step-by-step explanation:
Area is w*l
Perimeter is 2(w+l)
Replacing the information known in the problem you can get the length with the perimeter
P = 2(w+l)
25 = 2(2+l)
12.5 = 2 + l
10.5 cm = l
with the length now you can find the area
A = w*l
A = 2*10.5
A = 21 cm2
Answer:
-1
Step-by-step explanation:
y=y
x+5=-3x+1
x+3x=1-5
4x=-4
x=-4/4
x=-1
<u>Original function:</u>
<u>Added 2 to the original function:</u>
- y = 2x + 2, this shifted the graph 2 units up
<u>Subtracted 4 from the original function:</u>
- y = 2x - 4, this shifted the graph 4 units down
Answer:
24/49
Step-by-step explanation:
The options to get 2 of different color is picking blue then red or red then blue.
Starting with picking blue then red.
The chance to pull blue first is 3/7. Then since the marble is replaced the chance to pull red next is 4/7.
The chance to get those in that specific order is the product of the two fractions. (3/7) * (4/7) = 12 / 49
The second option of getting red then blue will be the same as above but 4/7 then 3/7 with the same result of 12/49.
To finish, add the two probabilities together 12/49 + 12/49 = 24/49.
