Difference Between Factors and Multiples. A factor is a number that leaves no remainder behind after it divides the specific number.
Lets solve your equation step by step:
(x+18)^1/2+2=x
step 1:Add -2 to both sides:
(x+18)^1/2+2-2=x+-2
(x+18^)1/2=x-2
step 2:solve exponent
(x+18)^1/2=x-2
((x+18)^1/2)^2=(x-2)^2
x+18=x^2-4x+4
x+18-(x^2-4x+4)=x^2-4x+4-(x^2-4x+4) (subtract x^2-4x+4 from both sides)
-x^2+5x+14=0
(-x-2)(x-7)=0(factor left side of equation)
-x-2=0 or x-7=0 (set factors equal to zero)
x=-2 or x=7

x=-2(doesn't work in original equation)
x=7(works in original equation)
Answer:
<h2><u><em>
15 cm</em></u></h2>
Step-by-step explanation:
Find the length of a square that is equal in area to a rectangle measuring 45cm by 5 cm
45 x 5 = 225 cm²
- length of the square = √A
√225 = <u><em>15 cm</em></u>
F(x) = x(2x-32) this is as standard form as it can get.
Work and Reasoning:
We start off with 12m
Since there are 9 ribbons each 0.4 meters you have to do 9 • 0.4. Since that is 3.6m.
To find out how much ribbon you have left you must subtract the amount he used against the amount he had to begin with.
12 - 3.6 = 8.4
To find out how many wreaths he can make, you must divide the remaining amount of ribbon he has by the 0.6 meter.
8.4 divided by 0.6 is 14.
Answer:
He can make 14 wreaths with the remaining amount of ribbon.
