Answer:
2x^2+4x+x-2
Step-by-step explanation:
use FOIL (first, outside, inside, last)
(2x-1)(-x+2)
2x(-x)=-2x^2
2x(2)=4x
-1(-x)=x
-1(2)=-2
2x^2+4x+x-2
Answer:
draw two blocks on top of each other being added together
Step-by-step explanation:
draw two blocks being added together...
Volume=(4/3)pi(r^3)
radius=1/2diameter
d=36
radius=1/2 36
radius=18
subsitute
volume=4/3 pi 18^3
volume=4/3 pi 5832
volume=23328/3 pi
volume=7776pi
aprox pi to 3.14
volume=7776 times 3.14
volume=24416.64
answer is 24416.64 yd^3
Answer:
Step-by-step explanation:
We have
So we find GCD = 1
2) By back substitution we get
71407 (543) - 19387(2000) =1
So x = 543 and y = -19387
Because we got 71407 (543) - 19387(2000) =1
y cannot be positive
y can only be negative
Answer:
Sale Price = $36
Step-by-step explanation:
To find the sale price, you need to find what 10% of the original price is. 10% of $45 is $4.50. Now we need to find what 20% is, 20% is double 10% so we multiply the answer we got by 2. This equals to $9. The question is asking for the sale price, to find it you have to subtract $9 (the discount) from $45 (regular price). The answer you should get is $36.
Equation:
$45 ÷ 10 = $4.50
$4.50 × 2 = $9
$45 - $9 = $36
