Answer:
875.018
Step-by-step explanation:
To solve this, we must plug in 6 for our t value. So, we have the equation:
-4.982 - 20(6) + 1000
Following the rules of PEMDAS, we have:
-4.982 - 120 + 1000 = 875.018
Answer:
17
Explanation:
(x + 8) + (8x + 1) = 90
Combine like terms to get:
9x + 9 = 90
Subtract 9 on both sides:
9x = 81
Divide by 9:
x = 9
Plug in 9 for x in
9 + 8 = ?
9 + 8 = 17
Answer:
4.8ft
Step-by-step explanation:
Let x be the length of the side of the hot tub. Ricardo wants the pool's sides to be 5 times as long, so
5x=24\implies x=\dfrac{24}5=4.8\text{ ft}
Answer:
you use the FOIL method
Step-by-step explanation:
First
Inner
Outer
Last
you just distribute the numbers to all of the others then simplify.
ex.
(x+4)^2
(x+4)(x+4)
x^2+4x+4x+16
x^2+8x+16
in this, x times x is x^2. then x times 4 is 4x and 4 times x is 4x and 4 times 4 is 16. then combine like terms
