Answer:
two hundred and forty million dollars for the supply at $40 a barrel.
Step-by-step explanation:
5-x>2
subtract 5 from both sides to get -x>-3
divide by -1 and flip the sign x<3
any number less than three satisfies the given equation
The side opposite the left 45 degree angle is 8 as well since the 2 base angles are equal.
Use s^2 + b^2 = c^2
Solve for c
8^2 + 8^2 = c^2
64 + 64 = c^2
128 = c^2
c = sqrt(128)
c = sqrt(64 * 2)
c = 8 sqrt(2)
c = 11.31

1. (3 + xz)(–3 + xz)
2. (y² – xy)(y² + xy)
3. (64y2 + x2)(–x2 + 64y2)
<u>Explanation</u>
The difference of 2 squares is in the form (a+b)(a-c).
<span>(3 + xz)(–3 + xz) = (3 + xz)(xz -3)
= (xz + 3)(xz - 3)
= x</span>²y²-3xy+3xy-9
<span> =x</span>²y² - 3²<span>
(y</span>² – xy)(y² + xy) = y⁴+xy³-xy³-x²y²
<span> = y</span>⁴ - x²y²
<span>
(64y2 + x2)(–x2 + 64y2)= (64y</span>²+x²)(64y²-x²)
= 4096y⁴-64y²x²+64y²x²-x⁴
= 4096y⁴ - x⁴
