Step-by-step explanation:
1. A = lw
- l = A/w
- l = (x²+7x +12) / (x + 3) =
- (x + 4)(x + 3)/(x + 3) =
- x + 4 m
2. V = lwh
- lw = V/h
- lw = (x³ + 12x²+ 47x + 60) / (x + 3) =
- (x³+ 3x² + 9x² + 27x + 20 x + 60) /(x + 3) =
- (x + 3)(x² + 9x + 20) / (x + 3) =
- x² + 9x + 20 cm²
3. A = bh
- h = A/b
- h = (f³-8) / (f-2) =
- (f - 2)(f² + 2f + 4)/(f-2) =
- f² + 2f + 4 cm
4. A = p*c
- c = A/p
- c = (3x³- 4x² + 2x + 4) / (x²- 2x + 2) =
- (3x³ - 6x² + 6x + 2x² - 4x + 4) /(x² - 2x + 2) =
- (x² - 2x + 2) (3x + 2) / (x² - 2x + 2) =
- 3x + 2 cans
5. A = lw
- l = A/w
- l = (x² + 5x - 6)/(x + 2) =
- (x - 1)(x + 6)/(x + 2) m
The metric system originated in France in 1799 following the French Revolution although decimal units had been used in many other countries and cultures previously. Although there have been many different measurements and the definitions of the units have been revised, the official system of measurements of most countries is the modern form of the metric system which is known as the "International System of Units".
Answer 4.6
Step-by-step explanation:
Okay, so you are talking about exponents, so what you are talking about is 2², to find the answer to the exponent you multiply the same number as many times as the exponent (little number) says, so in here we are going to multiply 2 x 2 and the answer is 4. So 2 to the power of 2 is 4.
Answer:
x = 24
Step-by-step explanation:
x - (3 · 4) = 12
x - 12 = 12
+ 12 + 12
x = 24
