Answer:
17.5
Step-by-step explanation:
Answer:
(2x + 11)(2x - 11)
Step-by-step explanation:
4x² - 121
rewrite the expression in the form of (a)² - (b)²:
(2x)² - (11)²
difference of squares a²-b²=(a+b)(a-b):
(2x + 11)(2x - 11)
Answer:
The interval where the product will at least break even is given by x ≥ 10.
In interval notation the interval will be denoted by [10, ∞).
Step-by-step explanation:
i) the cost to produce x units of wire is C = 55x + 450
ii) the Revenue is R = 80x
iii) therefore the product will at least break even when
the cost, C = the Revenue, R.
therefore 55x + 450 = 80x
(80 - 35)x = 45x = 450 ∴x = 450 / 45 = 10.
iv) The interval where the product will at least break even is given by x ≥
10.
In interval notation the interval will be denoted by [10, ∞).
Write the problem: 2x^2+3x-y-4y^2
Substitute x and y: 2(2)^2+3(2)-(-4)-4(-4)^2
Exponents and Multiplication: 8+6+4-64
Add and Subtract: -46
Your Answer is -46
