Answer:
20
Step-by-step explanation: -13 to 7 think about that. We have to add 13 to make it 0. Then we add 7. So 13 plus 7 is 20. Enjoy :)
Through trial and error:
(7x-6)(3x-2)
Usually it works best to test out a number of possibilities :)
Answer: Both plants grow at same rate ie., 4/3 cm per day
Step-by-step explanation:
8 cm = 6 days
1 day = 1/6 x 8 = 4/3 cm
12 cm = 9 days
1 day = 1/9 x 12 = 4/3 cm
Answer:
slope=2 and y intercept =1
Step-by-step explanation:
y=2x+1
y+2(0)+1
y=0+1
y=1
Answer:
lets use what we know.
given lengths are: 6, 3, 6, and 15.
We need to split the right triangle from the small little rectangle.
Now we add the lengths of the triangle to get the full length:
6 + 6 = 12
now we need to find the base:
15 - 3 = 12
Now we get our area of the triangle:
12 x 12 = 144
144 divided by 2 = 72
Now the small rectangle's area:
6 x 3 = 18
Add both of their areas to get:
72 + 18 = 90 ft2
