6. The height of a triangle is 2 units more than the base. The area of the triangle is 10 square units. Find

Harrizon [31]

Answer:

4.24

Step-by-step explanation:

First, let's set up the equation: $\frac{2+x^2}{2}=10$

Next, clear the fraction by multiplying both sides by 2: $2*(\frac{2+x^2}{2}=10)=2+x^2=20$

Then, subtract 2 from both sides: $x^2=18$

Finally, take a square root of both sides and round: $\sqrt{x^2=18} =$ (Rounded to the nearest hundredth) 4.24

Solve for n. n + 1 = 4(n – 8)

kolezko [41]

N + 1 = 4(n – 8)
Use distributive property for this part: 4(n – 8) ----> 4n - 32

n + 1 = 4n - 32

Get the variable on one side:

n + 1 = 4n - 32
-n -n

1= 3n - 32

Get the variable on its own:

1= 3n - 32
+32 +32

33 = 3n

Divide by 3 on both sides:

33/3 = 3n/3

n = 11

1kg= 2.2 pounds Change 44 pounds in kg

Lyrx [107]

Answer:
44 pounds = 20 kg

Explanation:
We are given that:
1 kg = 2.2 pounds

To convert 44 pounds into kg, all we have to do is cross multiplication as follows:
1 kg .................> 2.2 pounds
?? kg .................> 44 pounds

Now, we solve as follows:
4 kg = $\frac{44*1}{2.2} = 20$ pounds

Hope this helps :)
