Is 3 over 4 x b the same as 3xb qver 4?

It is difficult to answer the question because it is still ambiguous. Putting brackets in helps. So: (3 over 4) x b = 3/4*b = 3*b / 4 YES but 3 over (4 x b) = 3/(4*b) is not 3/4*b


What is 3 x b x 4?

12b


How do you solve x2-3x-28 equals 0?

You can use the quadratic formula for an equation of the form a*x^2 + b*x + c = 0. x = (-b +/- sqrt(b^2-4*a*c))/(2*a) In this case: a = 1 b = -3 c = -28 x = (3 +/- sqrt(9 - 4*(-28)))/2 x = (3 +/- sqrt(121))/2 x = (3 +/- 11)/2 x = 7 or -4 Another option is to attempt to simplify the equation into the form (x-a)(x-b) = 0. Sometimes you can do this by observation. For example: 28 = 4*7 7-4 = 3 Thus: (x-7)(x+4)=0 In this case, a and b are known as the "roots" of the equation, with a = 7 and b = -4.


How do you divide two numbers that are in scientific notation?

For example, (4.1076 x 10^3)/(2.8 x 10^4) = (4.1076/2.8) x [10 ^(3 - 4)] = 1.467 x 10^-1 or (4.1076 x 10^3)/(2.8 x 10^-4) = (4.1076/2.8) x [10 ^(3 - -4)] = 1.467 x 10^7


What is the sum of the prime factors of 81?

As a product of its prime factors: 3*3*3*3 = 81 and 4*3 = 12


How to solve x to the third times x to the fourth?

Use x^a * x^b = x^(a+b). x^3 * x^4 = x^7


What is the exponent form for 2x2x2x2?

A number a multiplied b times (so a x a is b=2, a x a x a is b=3, a x a x a x a is b = 4, and so on) is written as ab. Since 2 is multiplied 4 times, you have 24.


What property is (4 3) 12 12 (4 3)?

a(b + c) = ab + ac 4 x 53 = 4(50 + 3) = (4 x 50) + (4 x 3) = 200 + 12 = 212


A florist has 6 banksias 5 wattles and 4 waratahs all the flowers of each kind are different. In how many ways can she make a bunch of 10 flowers if she has to use at least 3 of each kind. 1200?

Must split 4-3-3. Banksia: 3 from 6 = 20, 4 from 6 = 15 Wattles: 3 from 5 = 10, 4 from 5 = 5 Waratahs: 3 from 4 = 4, 4 from 4 = 1 Possible combinations: 4 x B, 3 x each W: 15 x 10 x 4 = 600 4 x Wat, 3 each B & War: 5 x 20 x 4 = 400 4 x War, 3 each B & Wat: 1 x 20 x 10 = 200 Your 1200 is correct.


What are factors in an expression?

Factors aremultiplicativeterms (i.e., they multiply into all the terms). The easiest way to see this is by example.Example 1:a(b+cd)a is a factor and (b+cd) is a factorExample 2:x2 - 9 = (x-3)(x+3)(x-3) is a factor and (x+3) is a factorHopefully you are beginning to notice you can always wrap parenthesis around a factor without altering the order of operations.Example 3:2a(b)(9n-x)+8This is a trick one, but you can factor out a 2:2a(b)(9n-x)+8 = (1)(2)a(b)(9n-x)+(4)(2) = (2)(ab(9n-x)+4)The factors are: 2 and (ab(9n-x)+4)Example 4:If that +8 wasn't on example 3, what would the factors be?2a(b)(9n-x)They would be:2, a, b, and (9n-x)


Use your calculator to find the vertex of fx -2x2 -3x 7?

Did you mean f(x)=x2-2x+5 ? If so the x value of the vertex is found by using the formula x=-b/2a where a is the coefficient of x^2 and b is the coeffiecient of x x=-(-3)/(2*-2) =3/4 y=-2*(3/4)^2-3*(3/4)+7


How do you Calculate any five from eleven?

Any b from a is calculated as:a!/((a-b)!) x b!The ! sign indicates factorial. In your question a = 11 & b = 5In full the formula gives (11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2)/((6 x 5 x 4 x 3 x 2)(5 x 4 x 3 x 2)This simplifies a bit to (11 x 10 x 9 x 8 x 7)/(5 x 4 x 3 x 2) ie 55440/120 = 462.If they can be in any order then you have to multiply by 120...
