Answer:
Area = 84 in²
Step-by-step explanation:
In order to find the area of the rectangle, you need to first set up an equation to find the length based on the information already given in the problem. Since the perimeter = 40 and the formula to find perimeter of a rectangle is: P = 2W + 2L, where W = width and L=Length, we can solve for 'L' by putting in the values given:
P = 2W + 2L or 40 = 2W + 2(3W - 4)
The length of the rectangle is '4 less than 3 times the width'. This can be written as the expression '3W - 4'.
Distribute: 40 = 2W + 2(3W - 4) or 40 = 2W + 6W - 8
Combine like terms: 40 = 8W - 8
Add '8' to both sides: 40 + 8 = 8W - 8 + 8 or 48 = 8W
Divide both sides by '8': 48/8 = 8W/8 or 6 = W
Solve for L: 3W - 4 or 3(6) - 4 = 18 - 4 = 14
Since L=14 and W = 6, we can solve for Area using the formula: A = LxW or A = (14)(16) = 84in².

Step-by-step explanation:
<u>The scale factor is </u>
- 1 : 9.5×10²⁰ as we make our galaxy as small as 1 m.
<u>The distance to Andromeda would be:</u>
- 2.4×10²² * 1/9.5×10²⁰ =
- 2.4/9.5×10²²⁻²⁰ =
- 0.25×10² =
- 25 m
Hard question but took my time and i have come up with 1216800000
Complementary angles sum to 90°
the complement of 64° = 90° - 64° = 26°
Answer:
1296
Step-by-step explanation:
Evaluate the expression, m^n if
m = 6 and n= 4
m^n = 6^4
m^n = 6⁴
m^n = 1296
