Answer:
a^4 - 2a^2b^2 + b^4
Step-by-step explanation:
Here, we want to expand the given expression
Mathematically, we have this as follows;
(a^2-b^2)^2
= (a^2(a^2 - b^2) -b^2(a^2-b^2)
a^4-a^2b^2 - a^2b^2 + b^4
= a^4 - 2a^2b^2 + b^4
Area of B patios a.74.42. B.37.21. C.144
Length of side of patio A = 12 yards
Area of patio A which is a square :
[tex] =\tt side \times side[/tex]
[tex] =\tt 12 \times 12[/tex]
[tex]\color{plum} = \tt144 \: {yards}^{2} [/tex]
Thus, Area of patio A = 144 yards²
Length of side of patio B = 6.1 yards
Area of patio B which is a square :
[tex] =\tt side \times side[/tex]
[tex] = \tt6.1 \times 6.1[/tex]
[tex]\color{plum} = \tt37.21 \: {yards}^{2} [/tex]
Length of side of the second patio B = 6.1 yards
Area of this patio :
[tex] =\tt 6.1 \times 6.1[/tex]
[tex]\color{plum} = \tt37.21 \: yards[/tex]
Total area of Patio B :
= Area of first patio B + Area of second patio B
[tex] =\tt 37.21 + 37.21[/tex]
[tex]\color{plum} = \tt74.42 \: {yards}^{2} [/tex]
Thus :
▪︎Area of patio A = 144 yards²
▪︎Area of patio B = 74.42 yards²
▪︎Therefore, the correct option is (a) 74.42

Ayden and his children went into a grocery store and where they sell peaches for $0.75 each and mangos for $1.75 each. Ayden has $20 to spend and must buy no less than 16 peaches and mangos altogether. If Ayden decided to buy 7 mangos, determine the maximum number of peaches that he could buy.
Answer:
he can buy 10 peaches.
Step-by-step explanation:
7 mangoes will be 12.25. so you subtract his original money(20) from 12.25 which gives you 7.75. then divide 7.75 by 0.75(cost of a peach) and your answer will be 10(rounded off).

The measure of the minor arc BC is 63º. What is the measure of ZBAC?
Answer:
measure or arc BAC should be 297 degrees (with assumptions)
Step-by-step explanation:
Assumption 1: the cap Z in your question is actually an angle symbol
Assumption 2: A is the center of the circle
IF these assumptions are true, then the measure of arc BAC is 36 - 63 = 297 degrees
In the parallelogram below,
x = [? ]°
Z
339
1249
Answer:
23
Step-by-step explanation:
Angle x and the two given angles form a triangle. The interior angles of a triangle add up to be 180.
so
[tex]124 + 33 + x = 180[/tex]
[tex]157 + x = 180[/tex]
[tex]x = 23[/tex]
In the parallelogram below, the value of x is [tex]23^o[/tex] using the angle sum property .
The angle sum property states that:
The sum of all the interior angles of a triangle is [tex]180^o[/tex].
A parallelogram is a four sided figure in which opposite sides are equal and parallel.
Given that:
A parallelogram in which the measurement [tex]124^o[/tex] and [tex]33^o[/tex] is given.
The parallelogram is divided into two triangles.
The value of x can be calculated as:
[tex]x+ 33^o + 124^o = 180^o[/tex] (Angle sum property)
[tex]157^o +x = 180^o[/tex]
x =[tex]180^o- 157^o[/tex]
x = [tex]23^o[/tex]
Thus, the value of x is [tex]23^o[/tex].

a rectangle poster is 2/3 meters long and 1/2 meters wide what is the area of the poster in square meters
3+2x = 41
Need help
Show work
Answer:
x=16
Step-by-step explanation:
when solving for a variable, get the variables to one side of the equation and the numbers to the other side.
3+2x=41
*minus 3 from both sides of the equation to get rid of the number on the side of variables of the equation*
2x=38
to get one variable alone, divide the whole equation by 2
x=16

Use the figure above to solve for x
Answer:
x is equal to 7
Step-by-step explanation:
Because the two horizontal lines are parallel, we know that the angles at which they intersect the diagonal line will be identical.
We also know that on either side of the diagonal line, the sum of the angles between that and either of the horizontal lines will be 180.
In short, we know that the two values given have a sum of 180. With that we can quickly solve for x:
(x + 67) + (x + 127) = 180
2x + 194 = 180
2x = -14
x = 7

A sales person saw the car for 18,250 and their commission is 912 and $.50 what percentage of the sales price is their commission
Answer:
the percentage of the sales price that is their commission is 5 %.
Step-by-step explanation:
Given;
price of the car, P = $18,250
commission, = $912.5
Let the percentage of the sales price that is their commission = y%
The percentage of the sales price that is their commission is calculated as;
[tex]\frac{y}{100} \times 18,250 = 912.5\\\\18,250y = 91250\\\\y = \frac{91250}{18250} \\\\y = 5 \ \%[/tex]
Therefore, the percentage of the sales price that is their commission is 5 %.
