Answer:
12
Step-by-step explanation:
The base of the triangle is 24 cm.
To find the base of a triangle, we can use the formula for the area of a triangle: Area = (base * height) / 2. Rearranging the formula gives us: base = (2 * Area) / height. Plugging in the given values, we get: base = (2 * 36) / 3 = 24 cm.

The value of n in the given expression is -15
Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
For example : - 3y+4, 8u+8, 9i+5, a+2, a+c etc.
Given that, an expression, 9(n+3) =7n-3, we need to find the value of n
Solving for n,
9(n+3) =7n-3
Using distributive property,
9n + 27 = 7n -3
Combining like terms, by transposing,
9n - 7n = -3-27
2n = -30
Diving by 2 both sides
n = -15
Hence, the value of n in the given expression is -15

Answer:
D. 15x10^20
Step-by-step explanation:
The rule for scientific notation is that the coefficient has to be between 1 and less than 10. This means there is only one digit in front of the decimal. 15x10^20 should be written as 1.5x10^21 to follow the rule.
Answer:
Hey there!
e15 times 10^20 isn't written in scientific notation. For a number to be in scientific notation, the leading number must be between 1 and 10.
Let me know if this helps :)
