Answer:
x = 6
Step-by-step explanation:
11 = 1/2x + 8
-> Move 8 to left side
11 - 8 = 1/2x
3 = 1/2x
->We can switch sides so 1/2x is on the left and 3 is on the right
1/2x = 3
x = 3 x 2/1
x = 6
Answer:
9x^6y^9
Step-by-step explanation:
you multiply the term outside the bracket with each of the terms inside the bracket
eg.3×3x=9x
3×2y=6y
3×3=9
if there are like terms use the law of exponent to simplify it even further
Answer:
The area of the shaded portion is 123 cm^2
Step-by-step explanation:
Here, we want to find the area of the shaded portion
To find this, we subtract the area of the smaller inner rectangle from that of the outside bigger one
Mathematically, the area of a rectangle at any point in time is length * width
For the bigger one, we have;16 * 9 = 144 cm^2
For the smaller inner one, we have ;3 * 7 = 21 cm^2
The area of the shaded portion which is the difference is;
144-21 = 123 cm^2
