I'm guessing you have to simplify this?
You distribute 4 to whatever is in the parenthesis.
So
4•y=4y
4•6=24
And of course there's the 5y that stays the same.
You get 4y+24+5y
Which simplifies to 9y+24 because you can group the 4y and 5y together.
In the end, you get 9y+24.
Answer:
A = 153.94 sq mi
Step-by-step explanation:
In this scenario, we would be starting from the center point and searching the area of a square since the distance in every direction would the same 7 mi. This 7-mile distance would be our radius in this scenario. We now need to use the formula for the Area of a circle to calculate the search area. This formula is the following
A =
A =
A =
A = 153.94 sq mi
A total of 153.94 square miles must be searched.
I think the answer would be a.
2x+3y=45
x+y=10
Take the bottom equation and solve for y
x+y=10
Subtract x from both sides
y=-x+10
Substitute into the top equation
2x+3(-x+10)=45
2x-3x+30=45
Subtract 30 from both sides + add like terms
-x=15
Divide both sides by -1
x=-15
