2017年7月13日 · :. LCM = 3 xx 4 xx 5 = 60 It is not necessary to break these values into their prime factors. We can find the LCM by inspection. 3 and 5 are already prime, but we should notice that 3,4 and 5 do not have any common factors at all. The LCM must be divisible by all them, so there needs to be a 3, a 4 and a 5. :. LCM = 3 xx 4 xx 5 = 60 The LCM of any numbers is …

No mode (one of each number) Median is 5 (middle number Mean is 5 mean is the total divided by how many numbers 1+2+3+4+5+6+7+8+9=45 there are 9 numbers mean =45/9=5

2015年7月15日 · Factoring won't work very well, but the graph of a function is a great indicator of its types of roots. Since this is a quartic equation (it has degree #4#), we know it will have #4# total roots.

First, use this rule for exponents to rewrite the radical: #root(color(red)(n))(x) = x^(1/color(red)(n))# #(root(color(red)(4))(5))^5 = (5^(1/color(red)(4)))^5#

2018年8月10日 · f(x) = (x+5)^2(x-1)(x-2) = x^4+7x^3-3x^2-55x+50 If a polynomial function f(x) has zeros x = -5, x=1 and x=2, then it has factors (x+5), (x-1) and (x-2). If these were its only factors, then it would be a cubic. It is not clear from the question whether -5, 1 and 2 are supposed to be the only zeros. If so then one of them must be of multiplicity 2. In any case, a suitable quartic …

2018年4月3日 · b. 4/5 An entire packet of seeds would be equal to 1/4 of a packet times 4 (to equal 1 packet). Multiply the 4 by the 1/5 of a garden that can be covered by 1/4 of a packet 4*1/5=4/5 You can also set up a proportion where x is the unknown amount of garden that a full packet of seeds can cover (1/4)/(1/5)=1/x 1/5*1=1/4*x rarr Cross multiply and solve for x …

2016年6月4日 · x = 2, x = -2/5 The quadratic formula states that given a quadratic equation ax^2 + bx + c = 0 Its roots can be obtained using the equation below x = (-b +- sqrt(b^2 ...

2017年6月18日 · See below You can solve this by making a table of values. However, I will solve this more mathematically (sorta). The -5 part says that the y-intercept of this line is -5. The y-intercept is the point at which a line crosses the y axis. Therefore, x is always 0 for the y intercept. The 1/4x is implying that the slope or the gradient (same thing) of this line is 1/4. Therefore, …
