Answer:
Step-by-step explanation:
Your problem setup is correct. The triangle is isosceles, so the marked segments are the same length.
3x - 8 = 2x
You can solve this by subtracting 2x (from both sides) ...
x - 8 = 0
Then adding 8 (to both sides):
x = 8
MB = MA = 2x = 16.
Answer:
-3
Step-by-step explanation:
log 1/3 27= 1/3^x=27 this means we have to simplify it. 1/3= 3^-1 power. Thus, (3^-1)^x=3^3. This is equal to 3^-x=3^3 therefore x=-3
Answer: the expression for the width is x + 4
Step-by-step explanation:
The area of the rectangle is expressed as
Area = x² + 13x + 36 square meters.
The length is expressed as
L = x + 9 meters
To determine the expression for the width of the rectangle, we would factorize the expression for the area. Hence
x² + 13x + 36 = 0
We would find two numbers such that their sum or difference is 13x and their product is 36x². The two numbers are 9x and 4x. Therefore,
x² + 9x + 4x + 36 = 0
x(x + 9) + 4(x + 9) = 0
(x + 4)(x + 9)
Therefore, the expression that represents the width of the rectangle is x + 4
PEMDAS
multiply 2x2=4 and simplify the equation by looking for like terms to combine.
4+16x+y+34=0
4 and 34 are like terms so add them.
the simplified expression is 16x+y+38
Hi, the area of a rectangle is: A = L * W.
Question 1:
Area of surface of the swimming pool is: 1000 * 100, or 100,000 square feet.
Question 2:
Volume of a rectangular box is: V = L * W * H.
Volume of the swimming pool is: V = 1000 * 100 * 10, or 1,000,000 cubic feet.
Question 3:
Question 1 in powers of 10 is: 105
Question 2 in powers of 10 is: 106
