Answer:
-12x - 14y
Step-by-step explanation:
First I would move them side by side so I can see it better so:
-7x - 5x - 8y - 6y
now combine the x values together and the y values together:
-12x - 14y
Answer:
Step-by-step explanation:
a. 3-4x=-7-4x
3=-7. no solution
b. 15 - 2x = -7x
15 = -5x
x=-3. one solution
c. 7y-21=6y-21
y=0
1. -3x+4=-3x+7
4=7
2. 10+2x = 5x+2
8=3x
x=3/8
3. x+5=x+5
You actually can’t get the exact square root of a negative number, it is not 3 as 3 squared is 9 not negative 9. It is not possible to square a number to get a negative answer, that’s where all the “i” stuff comes in with irrational numbers.
Answer:
178 sq in
Step-by-step explanation:

Well, we know the formula for finding the area of a rectangle is B*H, and the formula for finding the area of a circle is πr^2
Let's find the area of a rectangle first:
25*6=150 sq in
Now the semicircles {which combined into one whole circle because they're two halves}:
The diameter is 6 inches, so the radius is 3 inches.
π(3)^2=9π
9*π=28.27 which can be rounded down to 28 sq in.
To fin the area of both, we would add them together:
150+28=178 square inches
