Answer:
2 x² - 6x -5
Step-by-step explanation:
Expansion:-
Given that the expression
(8x²-7x-2)-(6x²-x+3)
= 8x² - 6x² - 7x +x -2 -3
= 2 x² - 6x -5

Answer:
6) 15
7)5
8)120 degrees
9)60 degrees
10)9
Step-by-step explanation:
GHIJ is a parallelogram.
Opposite sides of a parallelogram are congruent.
3y - 1 = 2y + 1
3y - 2y = 1 + 1
y = 2
Opposite sides of a parallelogram are congruent.
4x + 3 = x + 12
4x - x = 12 - 3
3x = 9
x = 9/3
x = 3
6)GH = ?
GH = 4x + 3
GH = 4(3) + 3
= 12 + 3
= 15
therefore, GH = 15
7) HI = ?
HI = 2y + 1
= 2(2) + 1
= 4 +1
= 5
therefore, HI = 5
Opposite angles of a parallelogram are equal.
8) m(angle I) = 120 degrees...... (given)
therefore, measure of angle G = measure of angle I
therefore, m(angle G) = 120 degrees
Consecutive angles of a parallelogram are supplementary.
9) m(angle I) + m(angle J) = 180 degrees
120 + m (angle J) = 180
m(angle J) = 180 - 120
= 60 degrees.
The diagonals of a parallelogram bisect each other.
10) JK = 9 .........( given)
JK = HK
therefore, HK = 9

Answer:
7.5
Step-by-step explanation:
The square has 4 equal sides, so you take the p,(30) and divide it. 30/4 = 7.5
To check your answer add 7.5 four times since the square has 4 equal sides.
7.5 + 7.5 = 15
15 + 7.5 = 22.5
22.5 + 7.5 = 30

A pair of designer sneakers was purchased for $120. Since they were purchased, their price has decreased by 15%
Complete question :
A pair of designer sneakers was purchased for $120. Since they were purchased, their price has increased by 15%. What is the new price?
Answer:
$138
Step-by-step explanation:
Given that :
Initial price = $120
Percentage increase in price = 15%
The new price of sneakers:
Initial price + (percentage increase in price * initial price)
New price :
$120 + (15% * $120)
New price :
$120 + (0.15 * $120)
New price of sneakers :
$120 + $18
New price of sneakers = $138
Mrs. Anderson is building a model for a pool. The actual pool is 32 yards long and 28 yards wide. If the scale factor is 0.5 inch = 2 yards, find the length of Mrs. Anderson's model pool.

Answer:
area of parallelogram = 21
area of trapezoid = 32
Step-by-step explanation:
Hello There!
The first figure shown is a parallelogram and the following dimensions are given
base = 7mm
height = 3mm
The area of a parallelogram can simply be found by multiplying the base by the height
so Area = 7 * 3
7 * 3 =21 so the area of the parallelogram is 21 square millimeters
The second figure given is a trapezoid and the following dimensions are given
height = 4m
base 1 = 5m
base 2 = 11m
To find the area of a trapezoid we use this formula
[tex]A=\frac{a+b}{2} h[/tex]
where a and b are bases and h = height
given the dimensions all we have to do is plug in the values into the formula
[tex]A=\frac{5+11}{2} 4\\5+11=16\\\frac{16}{2} =8\\8*4=32\\A=32[/tex]
so we can conclude that the area of the trapezoid is 32 square meters

Can you guys please help
Answer:
The length (which is the bottom and top lines) are both 9 inches long.
Step-by-step explanation:
To find the perimeter with only one given measurement and the total perimeter, first you need to double the given value. In this case it is 6 so 6 x 2 = 12. After that you need to find the rest of the sides so you can do 30 - 12 = x, or 12 + x = 30. As a total the answer is 18. Finally you divide 18 by two because there is two sides and you get 9.

please help i dont understand
Answer:
t (is less than or equal to) 96
Step-by-step explanation:
to solve for t, you need it to be isolated. to move the 3 to the other side, you need to multiply it on both. 3 x t/3= t and 32 x 3= 96, therefore t (is less than or equal to) 96.
i hope this helps :)
Answer:
t ≤ 96
Step-by-step explanation:
t / 3 ≤ 32
(multiply both sides by 3)
t / 3 * 3 ≤ 32 * 3
t ≤ 96
Can someone help me with this question please? Many thanks in advance.
Jack, Alex and Amir jumped a total of 12.69 m in a long
jump competition.
Alex jumped exactly 200 cm further than Jack.
Amir jumped exactly 2,000 mm further than Alex.
What distance did they all jump?
Give your answers in metres.
Answer:
Step-by-step explanation:
The distances they jumped were
x,y,z
y=x+2
z=x+2+2=x+4
x+y+z=12.69
x+x+2+x+4=12.69
3x+6=12.69
3x=6.69
x=2.23
So Jack jumped 2.23m, Alex jumped 4.23m, and Amir jumped 6.23m.

Answer:
m(arc)RST = 154 deg
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
x + 77 + x + 103 = 180
2x + 180 = 180
2x = 0
x = 0
m<RST = x + 77 = 0 + 77 = 77
The measure of an inscribed angle is half the measure of its subtended arc.
m<RST = (1/2)m(arc)RST
77 = (1/2)m(arc)RST
154 = m(arc)RST
m(arc)RST = 154 deg
find the 9th term of the geometric sequence 6,-24,96...
Answer:
A9 = 393216
Step-by-step explanation:
the first thing that will help you solve this question is finding the common ratio between each terms
the first thing that I like to do that usually helps is to take the second term (-24) and divide it by the first term (6) --> this will usually help you spot the common ratio fairly quickly
in your case, the common ratio is -4
- you can also check this by following my note above and then multiplying the second term by the common ratio to see if it matches the third term, which it does!
so now you can go about this two different ways
1. solve directly for the 9th term
2. use the nth term formula for geometric sequences
METHOD 1:
if you continue to multiply by -4 to solve for each term you would end up with:
6, -24, 96, -384, 1536, -6144, 24576, -98304, 393216
and you will recieve 393216 as your answer
METHOD 2:
the nth term formula is An = A1*r^(n-1)
where An = the nth term of the sequence
A1 = first term of the sequence (6)
and r = common ratio
using this formula, you would get:
A9 = 6(-4)^8
A9 = 393216
I hope this helped :)
