Answer:
4(1+7x)
Step-by-step explanation:
There are 2 terms in this expression: Factorize them
4: 2 * 2
28x: 2 * 2 * 7 * [tex]x[/tex]
Which factors do both of the terms have in common?
2 and 2, which means that the GCF is 4.
Now to figure out whats inside the parentheses.
What number multiplied by 4 gives 4? 1
What number multiplied by 28x gives 4? 7x
So the final result is 4(1+7x)

STEP 4:Trying to factor as a Difference of Squares: 4.1 Factoring: 10x2-y2 Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)Proof : (A+B) • (A-B) = A2 - AB + BA - B2 = A2 - AB + AB - B2 = A2 - B2Note : AB = BA is the commutative property of multiplication. Note : - AB + AB equals zero and is therefore eliminated from the expression.Check : 10 is not a square !! Ruling : Binomial can not be factored as thedifference of two perfect squaresCalculating the Least Common Multiple : 4.2 Find the Least Common Multiple The left denominator is : y2 The right denominator is : x2 Number of times each Algebraic Factor appears in the factorization of: Algebraic Factor Left Denominator Right Denominator L.C.M = Max {Left,Right} x 022 y 202 Least Common Multiple: x2y2 Calculating Multipliers : 4.3 Calculate multipliers for the two fractions Denote the Least Common Multiple by L.C.M Denote the Left Multiplier by Left_M Denote the Right Multiplier by Right_M Denote the Left Deniminator by L_Deno Denote the Right Multiplier by R_Deno Left_M = L.C.M / L_Deno = x2 Right_M = L.C.M / R_Deno = y2Making Equivalent Fractions : 4.4 Rewrite the two fractions into equivalent fractionsTwo fractions are called equivalent if they have the same numeric value.

Ebony had a sum of money.
She kept ½ for herself. She decided to give the rest away to family and charity.
¾ of the money she gave away went to family.
a) What fraction of the total amount did Ebony give to charity?
a)If the amount was £200, how much money did she give to family?
Answer: She gave a fraction of 1/4 to charity, and she gave $150 to family
Step-by-step explanation: Ebony had a totaly of $200 dollars to start with to give away that means if she gave 3/4 of $200 to family that would mean she gave $150 dollars to her family
Now the other part of the question is how much of the total amount did Ebony give to charity now if I understand that part correctly then it wants you to give the fraction of the total which would be she gave 1/4 out of the $200 she had for family and charity which means she gave 1/4 of $200 which is $50 to charity

John has a bag of different colored marbles. He has 6 red marbles, 3 blue marbles, 7 yellow marbles, and 5 green marbles. If John reaches into the bag and randomly pulls out a marble, what is the probability that the marble will be blue? (If necessary, round to the nearest tenth.) (as a percent please!!)
Answer:
P(blue) ≈ 14.3%
Step-by-step explanation:
probability P is calculated as
P = ( favourable outcome ) ÷ ( total number of possible outcomes )
here favourable outcome is blue of which there are 3
number of possible outcomes is the total = 6 + 3 + 7 + 5 = 21
P(blue) = [tex]\frac{3}{21}[/tex] = [tex]\frac{1}{7}[/tex]
to convert to a percentage multiply the fraction by 100%
P (blue) = [tex]\frac{1}{7}[/tex] × 100% = 100% ÷ 7 ≈ 14.3% ( to the nearest tenth )
Answer:
14.3%

Two bags, A and B, each contain only green marbles and red marbles.
There are 6 green marbles and 4 red marbles in bag A.
There are 8 green marbles and 2 red marbles in bag B.
One marble is going to be taken at random from bag A and placed in bag B.
A marble is then going to be taken at random from bag B.
Work out the probability that this marble will be a green marble.
Using it's concept, it is found that there is a 0.7818 = 78.18% probability that this marble will be a green marble.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
There are two ways to end up with a green marble selected.
Green in bag A(6/10 probability) and in bag B(9/11 probability).Red in bag A(4/10 probability) and green in bag B(8/11 probability).Hence, the probability that this marble will be a green marble is given by:
[tex]p = \frac{6}{10} \times \frac{9}{11} + \frac{4}{10} \times \frac{8}{11} = \frac{54 + 32}{110} = 0.7818 = 78.18\%[/tex]

Given that x + y= 180, p + 9 = 180, and p = x. Show that y= q. 1) Which step would be used to prove the argument? es A) x + p = 180 B) x + y = p +9 (9y+ = 180 D) 2x + 2y = 180
Answer:x + y = 180
p + q = 180
p = x
Show that y = q
x = 180 - y
p = 180 - q
p = x
180 - q = 180 - y
-q = 180 - y - 180
-q = -y
-q/-1 = -y/-1
q = y OR y = q
x + y = p + q CHOICE B.
180 - y + y = 180 - q + q
