Answer:
-3n-+21
Step-by-step explanation: 1. Get rid of the Parenthesis , so times -3 by what’s inside
2. If you multiply -3 by n you get -3n
3. if you multiply -3 by -7 you get 21 , you get a positive because a negative times a negative is a positive
4. so now you have -3n + 21 you don’t add these because -3n has a variable and 21 doesn’t have a variable , and if 21 did have a variable it would need to also be n
Answer:
−3n + 21
Step-by-step explanation:
This is the answer because:
1) You have to distribute everything from outside of the parenthesis to the inside
2) -3 times n is -3n
3) -3 times -7 is 21
4) Therefore, the answer is −3n + 21
Hope this helps!

1643 is the annual premium for the cheapest policy Jeremy can buy.
The amount of money a business or an individual pays for a policy annually is called the annual premium.
Face value is the amount of benefits in the form of money or other beneficiaries a policy holder receives at maturity.
Age of Jeremy = 29
Face value of the policy = $90,000
Estimated annual premium = (Face value ÷ 1000) × rate
Annual premium payable for a man whole life = (90,000 ÷ 1000) × 18.25
= 90 × 18.25
= 1642.5 ≅ 1643
Hence, Annual premium for the cheapest policy having a 90,000 face value that Jeremy can buy is $1643.

Step-by-step explanation:
The given linear equation can be reduced, ending up as
y - x = 4 or y = x + 4
If we choose our own x values, we can calculate the corresponding y value in each case:
x y = x + 4 ordered pairs
0 4 (0, 4)
1 5 (1, 5)
3 7 (3, 7)
-2 2 (-2, 2)
To find the dimensions of a rectangle with the smallest possible perimeter given an area of 343 m², we must determine the dimensions that will minimize the sum of the lengths of the four sides. The dimensions of the rectangle are 7 m by 49 m.
To find the dimensions of a rectangle with the smallest possible perimeter given an area of 343 m², we must determine the dimensions that will minimize the sum of the lengths of the four sides. Since the perimeter is the sum of the lengths of the opposite sides of a rectangle, we can rewrite the perimeter formula as P = 2l + 2w, where l represents the length and w represents the width.
Now, let's solve for the dimensions:
1. Start with the formula for the area of a rectangle: A = lw.
2. Substitute the given area: 343 = lw.
3. Rewrite the perimeter formula: P = 2l + 2w.
4. Express one variable in terms of the other using the area formula: l = 343/w.
5. Substitute the expression for l in the perimeter formula: P = 2(343/w) + 2w.
6. Simplify the equation: P = (686/w) + 2w.
7. To find the minimum perimeter, differentiate the equation with respect to w and set it equal to zero: 0 = (686/w²) + 2.
8. Solve the equation for w: (686/w²) + 2 = 0. Subtract 2 from both sides: 686/w² = -2. Multiply both sides by w²: 686 = -2w².
9. Divide both sides by -2: -343 = w². Take the square root of both sides (ignoring the positive value since the width cannot be negative): w = -√343 = -7.
10. Substitute the value of w back into the area formula: 343 = l(-7). Solve for l: 343 = -7l. Divide both sides by -7: l = 343/-7 = -49.
Since both dimensions cannot be negative, we ignore the negative values and take the absolute values of w and l: w = 7 and l = 49.
Therefore, the dimensions of the rectangle with an area of 343 m² and the smallest possible perimeter are 7 m by 49 m.
