Please check your questions after you copy-paste!

Let be Sarah's age. We know that the difference between Sarah's age and 44 ----->

...Multiplied by 4 ---->

equals 64----->

To solve the equation, we divide both sides by 4:

And add 44 to both sides:

60 years old

Step-by-step explanation:

If she 48 is 4 times her age then we know that 48 divided by 4 is 16. We then add that to 48 to find out her actual age which is 60

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

the answer is:

mean: 6

mad: 2.14
