B first you add then multiply
Answer:
p = 7
Step-by-step explanation:
Step 1: Subtract 2p from both sides.
5p − 9 − 2p = 2p + 12 − 2p
3p−9=12
Step 2: Add 9 to both sides.
3p − 9 + 9 = 12 + 9
3p = 21
Step 3: Divide both sides by 3.
= 
p = 7
Answer:
C, C and A
Step-by-step explanation:
using the formulae relating to the circle
• Area (A) = πr² ( r is the radius )
• Circumference (C) = 2πr ( r is the radius )
(8)
Area of the interior with r = 4
A = π × 4² = 16π ≈ 50.27 ft² → C
(9)
Area of exterior with r = 7
A = π × 7² = 49π ≈ 154 ft² → C
(1)
Circumference of exterior circle with r = 7
C = 2 × π × 7 = 14π ≈ 44 ft → A
Answer:

Answer: Equation Classification
: A. Possible and Determined;
B. Possible and undetermined and C. Impossible:
Step-by-step explanation:
A. Possible and Determined: These are equations that admit at least one solution.
Example: 2x = 3 → x = <u>3
</u>
2
B.
Possible and undetermined:
They are equations that have infinite solutions.
Example: x + 2 = x + 2 → The unknown x assumes infinite numerical values. Thus, the equation has infinite solutions.
C. Impossible: Has no solution.
Examples:
0x = 4 → Unable to divide 4 by 0.
y = y + 2 → y - y = + 2 → 0 = +2 → There is no equation without unknown.
