Answer:
4x + 12 feet.
Step-by-step explanation:
If the side lengths of a kite are A and B, then the perimeter of the kite is given by P = 2(A + B)
Now, the side lengths of a given kite are 2 feet and 4 feet.
If side lengths are increased by the same number (say, x feet), then the side lengths of the kite will become (2 + x) feet and (4 + x) feet.
Therefore, the perimeter of the larger kite will be = 2[(2 +x) + (4 + x)] = 2(2x + 6) = 4x + 12 feet. (Answer)
Answer:
x (blue circle thing) = 46
y (dna) = -63
z (molecules) = 52
Step-by-step explanation:
Cows(m) have 4 legs, chickens(c) have 2. Setting up a system of equations 104=4m+2c and 42=m+c. Solved for c the latter equation becomes 42-m=c. Using substitution in the first equation 104=4m+2(42-m). Distribute: 104=4m+84-2m. Combine like terms: 104=2m+84. Isolate variable term: 104-84=2m. Variable coefficient 1: 20/2=10=m. 42-10=32=c. <u>10 cows and 32 chickens.</u>
