Answer:
y=x+12-10
Step-by-step explanation:
0=x+12-10
-x=2
x=-2
Given:
- A rectangle has a width that is 5 feet less than the length. The area of the rectangle is 126 square feet
❍Let's assume, Length of rectangle x feet and width of the rectangle x - 5 feet respectively.
To calculate the dimensions of the rectangle we will use the formula of Area of rectangle:
- We know that side can't be negative. So, x = 14 feet
Hence,
- Width of rectangle = x - 5 = 9 feet
- Length of rectangle = x = 14 feet
Answer:
A= 226.08
Step-by-step explanation:
The formula for the surface area of a cylinder is A=2πrh + 2πr^2
So, plug in the numbers. π(pi)= 3.14
A= (2 × 3.14 × 4 × 5) + (2 × 3.14 × 4²)
You could use a calculator for the last few steps.
Multiply what's in the first set of parenthesizes: I25.6
Now, multiply the numbers in the other pair of parenthesizes: 100.48
Lastly, add the two numbers together: 226.08
226.08 is the surface area of the cylinder.
Answer:
thats a rip off
Step-by-step explanation:
Answer:
angles 1 and 3 are 30
angles 5, 8, 10 and 12 are all 85
angle 11 is 95
angles 9 and 6 are 30
7 and 4 are 65
Step-by-step explanation:
angle 2 is congruent to 150, so 1 and 3 are: 360 degrees -150-150=x/2 to get the angles, then cos its an isosceles triangle due to the parallel lines, 9 and 6 are congruent to 1 and three, and 11 is 95 so you do 360 degrees-95-95=x/2 to get 85, then you take the 95 that is congruent to the angle group below it, and subtract 30 cos angles 9 and 4 are equivalent to the whole angle of 11, so yea u subtract 30 and you get 65, and you match up the congruent ones lol hope this helps ik its confusing
