Step-by-step explanation:
8x−5y=11 = Let's solve for x.
8x−5y=11
Step 1: Add 5y to both sides.
8x−5y+5y=11+5y
8x=5y+11
Step 2: Divide both sides by 8.
8x

=
5y+11

4x−3y=5= Let's solve for x.
4x−3y=5
Step 1: Add 3y to both sides.
4x−3y+3y=5+3y
4x=3y+5
Step 2: Divide both sides by 4.
4x

=
3y+5

Perimeter = 24
triangle perimeter = 2W + 2L
24= 2W + 2L
12 = W + L
L= 12-W
AREA = W*L
AREA = (W)(12-W)
A = 12W-W^2
maximum occurs when you take the derivative
d/dw=12-2w = 0
w=6
after this i think we can say 6 * 6 = 36 is the maximum area.. not to sure, havent done a problem like this in a while
hope this helps
or if we know what w=6 we can find L
L = 12-w which we still get 6<span />
Answer:
Step-by-step explanation:
i dont really get the question but
16 mm = 1.6 cm = 16/10 cm = 8/5 cm
Answer:
Step-by-step explanation:
First, in millimeters, so the first square is 2025, and the second square is 900. Add those to get 2925 mm. Then, look at the answers. Whichever one has 2925 mm squared first, then a smaller number, that's the one. Therefore, the answer is 2925 mm squared and 29.25 cm squared.
