Answer:
x = sqrt(5)
Step-by-step explanation:
The ratio of the areas is equal to the ratio of the side lengths squared
20 5^2
----- = -----
4 x^2
Using cross products
20 x^2 = 4 * 5^2
20x^2 = 4*25
20x^2 = 100
Divide by 20
20x^2 = 100/20
x^2 = 5
Take the square root of each side
sqrt(x^2) = sqrt(5)
x = sqrt(5)
The near future tense (le futur proche) is used to express something that will be happening in the very near future, and is formed by conjugating the verb aller (to go) into the present tense and pairing it with theinfinitive<span> verb. Here's a sample sentence in the near future tense: Je vais nager. (I am going to swim.)</span>
Answer:
D
Step-by-step explanation:
First subtract the 1 from both sides. this leaves you with a -2x on one side and a 2 on the other side. Divide the -2, and remember that when you divide a negative number, the sign in the middle flips meaning that the answer would be x is less than or equal to -1.
40 ÷ 5 = 8 ( how much 1 cd costs )
8 × 2 = 16
