#a. y - 5 = 2x
Add 5 to both sides to get,
y - 5 + 5 = 2x + 5
y = 2x + 5
Answer:
The area is 12.56, and the circumference is 12.56.
Step-by-step explanation:
For the area,
We need to use the formula A=3.14*radius*radius
So we plug it in, and we get 3.14*2*2, which is 12.56 centimeters squared.
For circumference, we need to do,
C = 3.14*diameter
To find the diameter we need to do 2 (radius) x 2 which is 4
Plugging it in that would be 3.14 * 4 which is 12.56
So, in this case, the area is 12.56, and the circumference is also 12.56.
Answer: First I suggest that you write out the all the proportions which govern the 3 right triangles involved.
Once you do that you will find this one:
PQ/PS =PR/PQ
PR=PS+SR
Substitution will give you this quadratic:PQ2=PS2+PS*SR
144=PS2+7PS which has only one solution which make sense, namely 9
Then QS=sqrt(144-81)

Answer:
56 HAHHHAH K.HFGIUWFV,
Step-by-step explanation:
8x + 84 = 500
8x = 416
