The two roots a + sqrt b and a - sqrt b are called conjugate radicals.
<u>Solution:</u>
Given that the two roots a + sqrt b and a - sqrt b are called ______ radicals.
Now let us write the each of the given two radicals in mathematical form.
So, first radical ⇒ a + sqrt b ⇒ 
[ since sqrt means square root]
Now second radical ⇒ a - sqrt b ⇒ 
We have to find the relation between 
Now, if observe is conjugate of 
[ where radical is eliminated]
Hence, the two roots a +sqrt b and a- sqrt b are called conjugate radicals
Answer:
3xy - xz, or x(3y - z)
Step-by-step explanation:
2x(y-z)+x(y+z) becomes
2xy - 2xz)+ xy + xz)
combining the xy terms, we get 3xy;
combining the xz terms, we get -xz
Thus, the complete simplified expression is 3xy - xz, or x(3y - z)
84.78
Explanation:
13.5•2=27
27•3.14=84.78
Each of them have 1 3/4 cups of flour, so together they have 2 x 1 3/4 cups. Turn the mixed number into an improper fraction in order to multiply it. 1 3/4 = 4/4 + 3/4 = 7/4. Multiply 7/4 x 2 = 7/4 x 2/1 = 7(2) / 4(1) = 14/4, which simplified equals 3 1/2 because 14/4 = 3 r2, or 3 2/4, which equals 3 1/2. So together they have a total of 3 1/2 cups of flour. Because 3 /12 is less than 5, they do not have enough cups of flour to make the recipe.
