What is 4r plus r in simplest form?
It is in its simplest form: 4r+r = 5r
What is the answer to 2r plus r plus 4g plus r?
4r+4g
What is the greatest common factor of 16r3 and 28r?
4r
2r plus 2s equals 50 and 2r minus s equals 17?
2r + 2s = 50 2r - s = 17 therefore 4r - 2s = 34 Add so that you can eliminate one of the variables: 2r + 2s = 50 4r - 2s = 34 ---------------- 6r + 0s = 84 Solve for r: 6r = 84 r = 14 Substitute r into one of the original equations: 2(14) + 2s = 50 28 + 2s = 50 2s = 22 s = 11 Doublecheck with the other original equation: 2(14) - 11 = 28 - 11 = 17
How do you keep the volume of a cylinder the same if the radius quadruples?
V = pi r^2*H & V = pi (4r)^2*h Equate pi r^(2)H= pi (4r)^2 h pi cancel down r^(2)H = (4r)^2h r^(2)*H = 16r^(2)*h 'r^(2) cancels down H= 16h h = H/16 This means is you increase the radius by '4 times' , then you reduce the height(H) by '16 times' in order to maintain the same volume.
What is the awnser of R plus 2s plus 3R?
It simplifies to: 2s+4R
What is -4r-9 plus r?
-13
How do you solve 7r equals 3r-52?
7r = 3r - 527r (- 3r) = 3r - 52 (- 3r)4r = - 524r / 4 = -52 / 4r = -13
3r plus 18 divided by 12 equals 4r - 48 divided by 4?
(3r + 18)/12 = (4r - 48)/4Multiply both sides by 12: (3r + 18) = 3*(4r - 48)or: 3r + 18 = 12r - 144Subtract 3r from both sides: 18 = 9r - 144Add 144 to both sides: 162 = 9rDivide both sides by 9: 18 = rAnswer: r = 18
Can you factor the polynomial 4r plus 8rs plus 28r?
4r + 8rs + 28r 4r is a factor of every every term so the expression can be written 4r(1 + 2s +7) NOTE : The original expression can be simplified to 8rs + 32r and thus the factored expression becomes 4r(2s + 8).
Solve 4r plus 3 equals 3r- 2 for r?
4r +3 = 3r-2 r + 3=-2 r=-5 basically collect terms so that you get one coefficient of r (in this case 4r on one side and 3r on the other. To get the three r over to the other side you subtract 3r on both sides.) Then r+ 3=-2, so that's simple algebraic manipulation.
What is 4r r in simplest form?
4r + 4 = 5r 4r - r = 3r 4r x r = 4r^2 4r/r = 4
Which expression is equivalent to 4(p r)-2p?
6
What is 4(2r plus 3s) - 4r?
It is 4r + 12s
What is the answer to -2 equals 4r plus s solving for s?
-2=4r+s s=-4r-2 or s=-(4r+2)
How do you slimpify 4r plus r?
Since 4R and R both contain a like term (R), you can combine them: 5R would be 4R plus R simplified
How do you solve this math problem r3-25r2-4r plus 100?
The question contains an algebraic expression. It is not an equation (or inequality) and so cannot be solved.
