N+3 evaluates to N+3
Multiply 10 by N+3
Multiply 10 by each term in N+3 term by term.
This is the distributive property of multiplication.
Multiply 10 and N
Multiply 1 and N
The N just gets copied along.
10 × N = 10N
Multiply 10 and 3
10 × 3 = 30
10*(N+3) evaluates to 10N+30
***The final answer is 10N+30***
Answer:
We expand a number to show the value of each digit.
29085:
20,000 + 9,000 + 000 + 80 + 5 = 29085

Since all three equations are equal, you take 15 x 20, which =300, once again because all of the equations are equal, take 300 and divide it by 5, that will give you your first question mark.{you should have gotten 60.} To find the second one, you are going to apply the same concept, Take 300 and divide it by 6, giving you your second question mark. {you should have gotten 50}...
P.S.: {hope I helped} :)
Answer:
An algebraic expression is an expression built up from constants,variables, and the algebraic operations.for example:3x^2-2xy+c is an algebraic expression.
Answer:
A) 220.5 mm^2
Step-by-step explanation:
<u>Explanation</u>:-
Given A regular triangular pyramid has a base of area is 31.5mm^2
and also given surface area of triangular pyramid is 252 mm ^2
by using formula
surface area of regular triangular pyramid = base of area + half of lateral surface.

252 = 31.5 + 

220.5 = lateral area of triangular pyramid
lateral area of triangular pyramid = 220.5 mm^2
