Answer:
b
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ← r is the radius
The circle shown is centred at the origin and has a radius of 5, thus
x² + y² = 5² ⇒ x² + y² = 25 → b
Yes, 10 squared+ 24 squared+ 26 squared
Answer:
<h2>
3p+6
</h2>
Step-by-step explanation:
8p+7−(5p+1)
=8p+7+−1(5p+1)
=8p+7+−1(5p)+(−1)(1)
=8p+7+−5p+−1
=8p+7+−5p+−1
=(8p+−5p)+(7+−1)
=3p+6
and thats how you get the answer

Answer:
8
Step-by-step explanation:
The numbers are 6 and 2x, then:
- 1/6 + 1/(2x) = 7/24
- 1/3 + 1/x = 7/12
- (x+3)/(3x) = 7/12
- 12(x+3) = 7*3x
- 12x + 36 = 21x
- 21x - 12x = 36
- 9x = 36
- x = 4
The other number is 2*4 = 8
