Hi Friend ✋✋✋
8 + 3 × 2 - 5
By BODMAS rule
8 + 6 - 5
= 9
Hope it helps
She has 15 left because she had 28 then she at 3 which is now 25 then she gave 5 away which is 20 then she gave 5 more away which is 15. So she ends up with 15
Answer:
Radius length: √5
Standard Form (Equation): (x + 4)^2 + y^2 = 5
Step-by-step explanation:
First we will determine the radius;
Center: (-4, 0)
Point on Circumference: (-2, 1)
d = √(-2 - (-4))^2 + (1 - 0)^2 = √(2)^2 + (1)^2
= √4 + 1 = √5
Therefore the radius is of length √5
Now the equation of a circle is in the form ((x - h)^2 + (y - k)^2) = r^2. The center is in the form (h,k) and r is the radius. Given this our equation would be (x - (-4))^2 + (y - 0)^2 = (√5)^2, or [simplified] (x + 4)^2 + y^2 = 5.
Use PEMDAS
Parenthasis
Exponents
Multiplication/Division (whichever comes first)
Addition/subtraction(whichever comes first)
First do whats in Perenthasis
16-9 is 7
now we have
18 + (7) ·4
Multiplication comes next in PEMDAS
do 7 x 4. Youll get 28
Now we have 18 + 28
Add them to get 46
The final answer is 46 :)
