We know that and are equal, and we're looking for their sum. First, we'll need to find the value of .
Set the expressions equal to each other:
Subtract from both sides:
Divide everything by :
Now that we have the value of , we can substitute it into the sum of the two expressions to get our final answer.
Substitute:
Simplify:
Answer:
-2
Step-by-step explanation:
35 = 5x + 45
So - 45 from both side
-10 = 5x
Divide both side by 5
-2 = x
X = -2
Answer:
27 cm
Step-by-step explanation:
So the ratio you have is
width(x) : length (36)= 3:4
Divide 36 (length) by the ratio length. 36÷4=9
They are multiples of nine, so multiply the width by 9 to get the 3.
3×9=27
You have 27:36
If you want to check it, divide both by 9 and you get 3:4
Answer:
x=0, 3/2, -1, -5/3
Step-by-step explanation:
The x-axis interception points of x(4x-6)(x+1)(3x+5): (0, 0), (3/2, 0), (-1, 0), (-5/3, 0)
The y-axis interception points of x(4x-6)(x+1)(3x+5): (0,0)
So the answer is 0, 3/2, -1, and -5/3.
Answer:
x = 0
Step-by-step explanation:
The goal is to isolate x. For this equation, you need to distribute the -3 to the terms inside the parentheses first. Then, add both sides by 12. Finally, divide the 24 by -3 in order to finally isolate x.
Thus, x = -8.
