What are the solutions of this system of equations? Select all that apply. y = x2 − x − 3 y = −3x + 5
The answer is 282 square units.
The surface area (SA) of the sum of the area of its base (A1) and 4 areas (A2) of the slant side. It is 4 because it is the square pyramid and it has 4 slant sides.
SA = A1 + 4A2
The area of the base (A1) is the area of the square with side a:
A1 = a²
The area of the slant area (A2) is of the square pyramid with side a and slant height s is:
A2 = a · s /2
So, it is known:
a = 10 u
s = 9.1 u
Therefore:
SA = A1 + 4A2 = a² + 4 · a · s /2 = a² + 2 · a · s = 10² + 2 · 10 · 9.1 = 100 + 182 = 282 u²

Answer:
Composite
Step-by-step explanation:
You can get 87 by multiplying 29x3 so that means it is composite because you cna multiply it by something other than 87x1
(0.1x + 0.4y)^2 =
(0.1x + 0.4y)(0.1x + 0.4y)
FOIL method
F (first)...multiply the first terms in each set....0.1x * 0.1x = 0.01x^2
O (outside)...multiply outside terms in each set...0.1x * 0.4y = 0.04xy
I (inside)...multiply inside terms in each set....0.4y * 0.1x = 0.04xy
L (last)...multiply last terms in each set...0.4y * 0.4y = 0.16y^2
now we have : 0.01x^2 + 0.04xy + 0.04xy + 0.16y^2....combine like terms
0.01x^2 + 0.08xy + 0.16y^2 <===
