Sep 25, 2015 · 20x^2sqrt(2x) Prime factors of 50 are 2 * 5 * 5 And x^5 = x^2 * x^2 * x Hence: 4sqrt(50x^5) = 4sqrt(2 * 5 * 5 * x^2 * x^2 * x) Since sqrt(5*5) = 5 and sqrt(x^2 * x^2) = x^2 4sqrt(50x^5) = 4*5*x^2sqrt(2*x) = 20x^2sqrt(2x)

Mar 8, 2018 · Break the trinomial into two binomials and solve for x in each of the binomials x^2 + 15x + 50 = ( x +5)xx( x +10 ) so (x + 5) xx ( x +10 ) = 0 x + 5 = 0 subtract 5 from both sides x + 5 - 5 = 0 -5 x = 5 x + 10 = 0 subtract 10 from both sides x + 10 -10 = 0-10 x = -10 The values for x are …

#2sqrt5 × 3sqrt10 = 2 × 3sqrt(5×10)=6sqrt50# #= 6sqrt(2·5^2)# # = 30sqrt2# Now if you want to divide, then the coefficients are divided among themselves and sub-radical amounts each other, placing the latter quotient under the radical common and the result is simplified. #2root3 (81x^7)# by #3root3( 3x^2)#

Mar 7, 2018 · 55 Add the first and the last numbers of the sequence and repeat for the other sets of numbers. 1 + 10 = 11 2 + 9 = 11 3 + 8 = 11 4 +7 = 11 5 + 6 = 11 This gives 5 sets of numbers that equal 11. 5 xx 11 = 55

Oct 11, 2014 · Electromagnetic radiation is made up of waves that are composed of photons which travel at the speed of light, c, in a vacuum, which is exactly 299,792,458 m/s, usually rounded to three significant figures as "3.00" x "10"^(8)"m/s". Ask your instructor for his or her preference. All electromagnetic waves have wavelength and frequency. The wavelength is the …

Jul 3, 2015 · x/2 We can represent a number in general by x. Halving a number means dividing it by two, so the expression that shows the half of a number is x/2, since you divide a number by two.

Jun 24, 2016 · 40/50xx100=80% x is the numerator = 40 y is the denominator = 50 z is the numerator as a percentage of the denominator = 80% The algebra: Divide x by y to get z/100 x/y=z/100 Multiply z/100 by 100 to get z z/100xx100=z How it works: 40/50=80/100=0.8 80/100xx100=0.8xx100=80 40 is 80% of 50.

Mar 26, 2018 · See a solution process below: "Percent" or "%" means "out of 100" or "per 100", Therefore x% can be written as x/100.

Nov 8, 2016 · s = 4.5 Step 1) Expand the terms in parenthesis. Step 2) Combine like terms Step 3) Solve for s while keeping the equation balanced 3s + 10s - 2 = 56.50 (3 + 10)s - 2 = 56.50 13s - 2 = 56.50 13s - 2 + 2 = 56.50 + 2 13s = 58.50 (13s)/13 = 58.50/13 s = 4.5
