First we use the quation given to solve for y.
-2y + 6 = 2 ------> Subtract 6 from both sides. (-6+2=-4)
-2y = - 4 ------> Divide both sides by -2 (-4/-2=2)
y = 2
Now you substitute the value of y or 2 into the first expression.
9(2)-9----> Multiply
18-9------->Subtract
9
Answer:
x^2+10x+21
Step-by-step explanation:
Blue box: x*x=x^2
Green box: x*3=3x
Purple box: 7*x=7x
Orange box: 7*3=21
x^2+(3x+7x)+21
Combine like term
A: x^2+10x+21
Answer:
343 cm ^3
Step-by-step explanation:
A cube has 6 squares of equal sizes. 294/6 = 49
The area of one square is 49
Since the area is the length squared, the square root of 49 is 7.
Volume of a cube is area times height. 49 x 7 = 343 cm^3
3=4m+ b
-1=3m+b
m=4
plug in to either equation,
3=16+ b
b=-13
Thus, C would be the answer.
I think its 180/24 here is my work
so you find the lcm of
