Answer:
w=1.5 or w=13.5
Step-by-step explanation:
this is one answer:
multiply w on both sides to leave u with
4.5=3w
divide both sides by 3
1.5=w
_____________________
this is the second one if the first one is wrong:
multiply 4.5 on both sides so that the 4.5/w would leave u with just only w alone.
then 3*4.5=13.5
w=13.5
hope dis helps if not then im not dat smart enough ;?
Answer:
Original rectangle: Since the area of a rectangle is the length * width, the area of this rectangle is 7 * 2 = 14 square cm.
New rectangle: The new dimensions of this are 7*3 = 21 cm by 2*3 = 6 cm. To find the area, we multiply these two together. 21*6 = 126 square cm.
126 is 9 times greater than 14, so the area will be multiplied by 9.
Step-by-step explanation:
Answer:
The expression is true.
Explanation:
We know that (a +b)(a-b) = a²-b²
So we have ,
Which is Right Hand Side given.
So, the expression is true.
The first step for finding out whether or not this expression is equivalent to
is to reduce the fraction with
. You can begin to do this by dividing the terms with the same base by subtracting their exponents.
Subtract the exponents.
Now reduce the fraction with
by doing the same process. Since I just showed you how to do this,, I will skip over this.
Since we cannot simplify this expression any further,, your answer is going to be
,, which is not equivalent to
.
Let me know if you have any further questions.

Answer:
a = 33 degrees
Step-by-step explanation:
Note that 57 degrees and Angle a are complementary: they add up to 90 degrees.
Thus, a = 90 degrees less 57 degrees = 33 degrees
