Answers
Answer:Equation at the end of step 1
STEP

:
4a2 - b2
Simplify ————————
2a - b
Trying to factor as a Difference of Squares:
2.1 Factoring: 4a2 - b2
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 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 4 is the square of 2
Check : a2 is the square of a1
Check : b2 is the square of b1
Factorization is : (2a + b) • (2a - b)
Canceling Out :
2.2 Cancel out (2a - b) which appears on both sides of the fraction line.
Final result :
2a + b

this year Benny is 12 years old and his mom is 48 years old what percent of his mom's age is Benny's age
Answers
Answer:
25%
Step-by-step explanation:
Let's set up a percent proportion:
12/x = 48/100
To solve for x, we would do:
x = (12*100)/48 = 1200/48 = 25
x = 25%
In my opinion, the easiest way to do this would be to look at this and notice that 12 * 4 =48 so that means 12 is 1/4 of 48 and 1/4 = 25%.
Let me know if you have any questions.

James is a botanist studying the production of beans by two types of bean plants.
He noticed that the string bean plant produced 30% more beans than the lima bean
plants. Based on James' observation, if the string bean plants produced 130 string
beans, how many lima beans did the lima bean plant produce?
Answers
Answer:
100 lima beans
Step-by-step explanation:
We can write an equation with s = string beans and l = lima beans:
s = 1.3l
We can now plug in 130 = s to get:
130 = 1.3l
We divide both sides by 1.3 and get:
100 = l
That means the lima bean plant produced 100 lima beans
Answer:
91
Step-by-step explanation:
130 * 30% =
130 * 0.3 =
39
130 - 39 = 91
A group of students are going on a trip and the trip costs $36.50 per student which includes $9.50 for lunch, an entrance ticket and a gift coupon. The gift coupon costs $50 for the entrance ticket. The cost of an entrance ticket is
A) $27.00
B) $25.00
C) $18.00
D) $13.50
Answers
Answer:
The answer is D) $13.50
Step-by-step explanation:
So first what you're gonna do it subtract $9.50 from $36.50 which will get you to $27.00.
Then you'll have to figure out what half of $27.00 is.
That will get you to the answer of D) $13.50

A) AA similarity
Step-by-step explanation:
AA stands for "angle, angle" and means that the triangles have two of their angles equal.
SAS stands for "side, angle, side" and means that we have two triangles where the ratio between two sides is the same as the ratio between another two sides and we we also know the included angles are equal.
SSS stands for "side, side, side" and means that we have two triangles with all three pairs of corresponding sides in the same ratio.
Here we can easily see that two angles are equal
∠CYK and ∠KZP∠CKY and ∠PKZ (they're cross angles)Therefore it's AA similarity

Answer:
y=4x
Step-by-step explanation:
y=mx+b is our frame equation for a linear function.
b=the y intercept, or when the line crosses the y axis, whenever x=0, so in this chart it is (0,0), b=0
y=mx+0
m= the slope, to find m you can either use the slope formula or plug in a point and solve for m
8=m(2) + 0
m=4
