Write two different expressions to represent the perimeter of this square. What can you conclude from the two expressions? Express your answer in two or more complete sentences.

s+s+s+s or s times 4

Step-by-step explanation:

The perimeter of a square is equal to 2l + 2w. In this case, 1l and 1w is equal to s. so 2(s) + 2(w) = 4s

P = 2a + 2a or P = 4a

As the opposite sides of the square are equal, so the perimeter will be given by P = 2a + 2a

Again the square has four sides equal, so the perimeter will be given by P = 4a. (Answer)

Step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
