Answer:
$14
Step-by-step explanation:
given
Sharif : Jose ---> 2:7
this means that:
Fraction of total that Sharif gets = 2 / (2+7) = 2/9
Fraction of total that Jose gets = 7 / (2+7) = 7/9
we are given that Jose gets $49, hence
jose's fraction = 7/9 , represents $49
i.e
7/9 -----> $49
1/9 -----> $49 ÷ 7 = $7
Sharif's fraction = 2/9 -----> $7 x 2 = $14
Answer:
B
Step-by-step explanation:
Divide both 28x and -4 by 4 because a square has 4 equal sides. That comes out to 7x-1, therefore answer B is correct.
Since we are to complete the square, therefore I believe
the correct given should be:
x ^ 2 – 11 x
Take note of the symbol ^ which denotes that 2 is an exponent
of x.
The general form of a binomial equation is in the form of:
a x^2 + b x + c
Where in this case:
a = 1
b = -11
c = unknown
To complete the square, we have to find for the value of
c. This is calculated using the formula:
c = (b / 2) ^ 2
c = (-11 / 2) ^ 2
c = 30.25
Therefore the complete equation is:
<span>x ^ 2 – 11 x + 30.25</span>

Answer:
Jaime: yes: 29·31 = 900 -1 = 899
Raquel: 24·26 = 25^2 -1 = 624
Step-by-step explanation:
The difference of squares factors as the product of the sum and difference of the roots:
a^2 -b^2 = (a -b)(a +b)
<u>Jaime</u>
29·31 = (30 -1)(30 +1) = 30^2 -1^2 = 900 -1 = 899
Jaime can subtract 1 from 30^2 to find 29·31
__
<u>Raquel</u>
24·26 = (25 -1)(25 +1) = 25^2 -1^2 = 625 -1 = 624
Raquel can subtract 1^2 from 25^2 to find 24·26.
