Answer: A. 5.6267 X 10^8
Step-by-step explanation:
(5.62 X 10^8) + (6.7 X 10^5)= 562670000
Which has 8 numbers after 5
5.6267 X 10^8 has 8 as well just minus the zeroes
The surface area of the monument shaped like a square pyramid is 14 m².
<h3>
Area </h3>
Area is the amount of space that is occupied by a two dimensional shape or object.
From the diagram
Area of each triangle = (1/2) * base * height = (1/2) * 2 * 2.5 = 2.5 m²
Area of square = length * length = 2 m * 2 m = 4 m²
Surface area of monument = 4(2.5) + 4 = 14 m²
The surface area of the monument shaped like a square pyramid is 14 m².

Okay we’re gonna do the order of PEMDAS. Here is my work! I hope you have a great day or night or whate it is for you.
Answer:
1) When x is 1, y is 4, and vice versa
2) When x is -6, y is 42, and when x is 7, y is 114
3) When x is -2, y is 2, and when x is 8, y is 42
Step-by-step explanation:
1)

which can be rearranged as
.
Substituting this lone y into the first equation, you get:

Move everything to one side:

Factor:



2)
which can be rearranged as
.

Let's use elimination this time and subtract the first equation from the second:

Factor:



3)


Let's set the two equations equal to each other through substitution:

Move everything to one side:

Factor:



Hope this helps!
