Answer:
2 and 4, 4 and 8, 16 and 32
Step-by-step explanation:
Answer: Choice B) 3 years
--------------------------------------
Explanation:
The simple interest formula is
i = P*r*t
where,
i = interest
P = principal
r = interest rate in decimal form
t = time in years
In this case,
i = 840
P = 7000
r = 0.04 (move the decimal point 2 spots to the left go to from 4% to 0.04)
t = unknown; we'll leave it as t
Plug the given values above and solve for, or isolate, t
i = P*r*t
840 = 7000*0.04*t
840 = 280*t
840/280 = 280*t/280
3 = t
t = 3
It will take 3 years
Answer:
D
Step-by-step explanation:
Any input that has 2 or more outputs is not a function. Since D is the only graph that has two or more lines "overlapping" each other, it is not a function.

Answer: (x+10) to the seccond power
Step-by-step explanation: 1
Use the sum-product pattern
x^{2}+{\color{#c92786}{20x}}+100
x^{2}+{\color{#c92786}{10x}}+{\color{#c92786}{10x}}+100
2
Common factor from the two pairs
x^{2}+10x+10x+100
x(x+10)+10(x+10)
3
Rewrite in factored form
x(x+10)+10(x+10)
(x+10)(x+10)
4
Combine to a square
