Answer:
The resultant expression would be 22 - 12x
Step-by-step explanation:
Let x be the unknown number,
Six plus four times a number = 6 + 4x
Four times four minus four times the number number = 4(4 - 4x)
Thus, Six plus four times the number plus four times four minus four times the number number = 6 + 4x + 4(4 - 4x)
Using distributive property,
6 + 4x + 16 - 16x
Combining like terms,
22 - 12x
Answer: 530 cm^2
Step-by-step explanation:
A = 3.14 * r^2
A = 3.14 * 13 * 13
A = 3.14 * 169
A = 530 cm ^2
Answer:
the answer should be 12
Step-by-step explanation:
4. Here you would use the Pythagorean Theorem. a² + b² = c²
In this case a and b are the same, so : a² + a² = c² would also work.
a = 5√2 so: (5√2)² + (5√2)² = c²
Do you know where to go from here?
It would be an 8 percent discount because 115 is 92 percent of 125.
