Answer:
Step-by-step explanation:
To factor by grouping, first divide the polynomial into 2 groups with parentheses.
Factor the greatest common factor (GCF) out of both binomials.
For the first binomial, the GCF is x.
For the second binomial, the GCF is 2.
Factor out the common binomial which is (x-5).
The factorized form of x²-5x+2x-10 is (x+2)(x-5)
Answer:
Jose and George are correct
Baulus is incorrect
Step-by-step explanation:
Given
%
Required
Compare the above expression with
Jose: 6.75%.
George: 0.0675
Baulus: 0.0675%
<em>The expression </em><em>% is given as a mixed fraction;</em>
In Jose's case, he simply converted it to decimal
Converting % to decimal;
First, we need to convert to improper fraction
% in improper fraction is
%
Then, we divide the numerator by the denominator
% = 6.75%.
Hence, Jose is correct
In George's case, he solved further by removing the % from Jose's answer.
% means divided by 100; In other words, x% means that we divide x by 100
So, 6.75% means we divide 6.75 by 100
= 0.0675
Hence, George is also correct
But same can't be said of Baulus;
Baulus converted % as 0.0675%
This means that he converted as 0.0675 then he appended it with the percentage sign (%)
Since is not equal to 0.0675, then we can conclude that Baulus is incorrect
