Answer:
x² + 4xy + 4y²
Step-by-step explanation:
(x + 2y)² = (x + 2y)(x + 2y)
Each term in the second factor is multiplied by each term in the first factor
(x + 2y)(x + 2y)
= x(x + 2y) + 2y(x + 2y) ← distribute both parenthesis
= x² + 2xy + 2xy + 4y² ← collect like terms
= x² + 4xy + 4y²
The interest is $175
The formula we'll use for this is the simple interest formula, or: I=P*R*t
Where:
<span><span>P is the principal amount, $5000.00.
</span><span>r is the interest rate, 7% per year, or in decimal form, 7/100=0.07.
</span><span>t is the time involved, 6....month(s) time periods.
</span><span>Since your interest rate is "per year" and you gave your time interval in "month(s)" we need to convert your time interval into"year" as well.
Do this by dividing your time, 6- month(s), by 12, since there's 12 months in 1 year. </span><span>So, t is 0.5....year time periods.
</span></span>
To find the simple interest, we multiply 5000 × 0.07 × 0.5 to get that: $175

Step-by-step explanation:
Answer:
10 grams equals 10,000 milligrams
Step-by-step explanation:

Answer:
perimeter: 42 in.
Step-by-step explanation:
separate the triangle, in the smallest triangle find the missing length of that side (hypotenuse: 13, short leg: 5, long leg: ?), which is (long leg) 12 in. (a^2+b^2=c^2 then 5^2+b^2=13^2) do the same process with the other half of the triangle. and you have your answer. hope this helped :)
