Step-by-step explanation:
Answer:
Well B is the base of the shape
If thats what you mean
Step-by-step explanation:
The surface area of the square pyramid if the length of the sides of the base are 10 cm, and the slant height is 15 cm is 416.2 cm²
<h3>Surface area</h3>
Surface area of the square pyramid
= a² + 2a√a²/4 + h²
where,
- a = sides of base = 10 cm
- h = slant height = 15 cm
Surface area of the square pyramid
= a² + 2a√a²/4 + h²
= 10² + 2(10)√10²/4 + 15²
= 100 + 20√100/4 + 225
= 100 + 20√25 + 225
= 100 + 20√250
= 100 + 20(15.81)
= 100 + 316.2
= 416.2 cm²

<span>let's say, you have 2(x+5)=10
What you do is multiply the x and the 5 by 2 so it now looks like
2x+10=10
The act of multiplying the inside numbers by the number outside the parenthesis is the distributive property. Now using distributive property to remove grouping symbols is similar
</span>Lets say you have 18 + {2 + 3 (6 -1*2)} first you would multiply 2by1
= 18 + {2 + 3(6 - 2)} then subrtact 2 from 6
= 18 + {2 + 3(4)} then multiply 3by 4 take away () grouping signal
= 18 + {2 + 12} then add 2 and 12
= 18 + {14} then take away the last grouping signals
= 18 + 14 then add 18 and 14
= 32
Answer:
(f+g)(2)=5
Step-by-step explanation:
Subsitute 2 in for x in both functions. Then add the answers of the functions together.
