Write the product as a trinomial.

(x + 2)(x + 4)

x2 + 8x + 8

x2 + 8x + 6

x2 + 6

x2 + 6x + 8

D, x² + 6x + 8

Step-by-step explanation:

to write (x + 2)(x + 4) as a trinomial, we can use FOIL to expand the equation, which stands for:

First terms

Outside terms

Inside terms

Last terms

i have higlighted the terms i am multiplying in bold to follow the steps easier

F: (x + 2)(x + 4)

x²

O: (x + 2)(x + 4)

4x

I: (x + 2)(x + 4)

2x

L: (x + 2)(x + 4)

8

we have the following equation:

x² + 4x + 2x + 8 < combine like terms

x² + 6x + 8 is our trinomial, so that is answer choice D

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

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.
