Will mark brainliest, need help asap! Build and sketch each expression below as a rectangle if possible. Then write an equation showing that the area is equal to the product of its side length factors. Check by multiplying the factors to get the original expression. If the expression can not be built as a rectangular area, explain why no rectangle exists and thus why the expression cannot be factored.

a. 2x^2 + 7x + 6

b. 6x^2 + 7x + 2

c. x^2 + 4x + 1

d. 2xy + 6x + y^2 + 3y

it is true

step-by-step explanation:

all the combinations add up i used   calculator

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.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
