Step-by-step explanation:
if a rectangle has 4 sides and there are two lengths and two widths
then we could split 80 by 2 and minus 4 from the length and then split that into two.
then your answer would be and 36 and 44
and the total answer would be half of each so the L=22 and L=22
and the W=18 and W= 18

Answer:
8) ΔCAB ~ ΔFDE; SSS
9) ΔMNQ ~ ΔPNO; SAS
10) ΔDBE ~ ΔABC; SAS
Step-by-step explanation:
8) The side ratios, shortest to longest, are ...
6 : 8 : 10 = 9 : 12 : 15 = 3 : 4 : 5
so are the same for both triangles. Triangles CAB and FDE are similar by SSS.
__
9) MN/NQ = PN/NO = 6/5 = 12/10. The vertical angles between these corresponding sides are congruent. Triangles MNQ and PNO are similar by SAS.
__
10) BD/BA = BE/BC = 21/28 = 24/32 = 3/4. The shared angle between the corresponding sides is congruent to itself. Triangles DBE and ABC are similar by SAS.
what is 3y-6=5y+6 answer plz
Answer:
y = − 6
Step-by-step explanation:
Solve by substitution.
y = 2.3 - 11
-2 + y = -4
Solution:
Answer:
Number 1: -8.7. Number 2: -2
Step-by-step explanation:
To find the first one, subtract 11 from 2.3.
2.3-11= -8.7 , so that's the answer for the first one.
To find the answer to the second one, just do -4+-2=-2, so that's the answer for the second one.

Can someone plz help me with this and explain how to do this math problem
Answer:
greater
Step-by-step explanation:
the reason is because if you allow x to have a value that is less than 3,
[tex] \sqrt{x - 3} [/tex]
will produce a square root of a negative number, and the square root of a negative number requires the use of imaginary numbers, therefore limiting x to greater than or equal to 3 prevents this, also, consideration should be given to the fraction
[tex] \frac{3}{x + 2} [/tex]
if x has a value of -2 it causes the denominator of the fraction to be 0, the denominator should never be 0, by limiting x to greater than 3 to prevent the problem above you are already taking care of x not being able to be -2 since greater than 3 already excludes -2

Done!
Any questions just leave them in the comments and I will answer.
Answer:
Step-by-step explanation:
i think you do 34x + 12
bc it is a same side interior angle and i think that equals 180 and then you
34x+12=180
-12 - 12
34x= 168

I got it wrong just for enjoy
if square ABCD were Rotated 90 clockwise about the origin to create square A’B’C’D. The measure of angle B is: D. 90.
Measure of angle
Given
ABCD=90 Clockwise
Hence:
Rotation will not change the size and figure
Square ABCD≅ Square A’B’C’D
m∠B=90°
So,
m∠B'=m∠B=90°
Therefore the correct option is D.

14. The equation of the line that passes through the
points (-2,2) and (3, -3) is
1. x + y = 5
2.x-y=5
3. y - x = 5
4. y = x
5. y = -X
Answer:
5. y = -x
Step-by-step explanation:
First, you need to find the slope of the line.
[tex]m = \frac{2 - (-3)}{-2 - 3} = \frac{5}{-5} = -1[/tex]
Now, using either point substitute into the point-slope form for a line:
[tex]y - y_{1} = m(x - x_{1} )[/tex]
Using (-2,2) for [tex](x_{1} , y_{1} )[/tex] we get y - 2 = -1(x +2)
y - 2 = -x - 2
y = -x

Two students, Abby and Melissa go for a walk. Abby begins walking 30 seconds earlier than Melissa .
-Abby walks at a speed of 8 feet per second.
-Melissa walks at a speed of 9 feet per second.
Abby had been walking for BLANK seconds when both students had walked exactly the same distance. (round to the nearest whole)
please help me
Answer:
270 seconds
Step-by-step explanation:
Melissa's time = x seconds
Abby's time = (x + 30) seconds
Abby walks at a speed of 8 feet per second, and Melissa walks at a speed of 9 feet per seconds.
But, speed = [tex]\frac{distance}{time taken}[/tex]
For Abby,
8 = [tex]\frac{distance}{(x + 30)}[/tex]
distance = 8(x + 30) ................. 1
for Melissa,
9 = [tex]\frac{distance}{x}[/tex]
distance = 9x ............. 2
From equations 1 and 2, for the same distance;
8(x + 30) = 9x
8x + 240 = 9x
x = 240 seconds
Abby's time = (x + 30)
= (240 + 30)
= 270 seconds
So that Abby has been walking for 270 seconds when both students had walked exactly the same distance.
The time taken is 270 seconds.
Given that,
Two students, Abby and Melissa go for a walk. Abby begins walking 30 seconds earlier than Melissa . Abby walks at a speed of 8 feet per second. Melissa walks at a speed of 9 feet per second.Here we assume Melissa time be x and Abby time be x + 30Based on the above information, the calculation is as follows:
8(x + 30) = 9x
8x + 240 = 9x
x = 240
So Abby time should be
= 240 + 30
= 270

x = - 6
Step-by-step explanation:
Equation
1/3 * (-9x +12) = 22 Multiply both sides by 3
Solution
3 * 1/3(-9x + 12) = 22*3
- 9x + 12 = 66 Subtract 12 from both sides.
-9x = 66 - 12 Combine
-9x = 54 Divide by -9
x = 54/-9

Solve the simultaneous equations by substitution
3y - 2x = -7
5x + 3y = 28
Answer:
(5, 1 )
Step-by-step explanation:
Given the 2 equations
3y - 2x = - 7 → (1)
5x + 3y = 28 → (2)
Rearrange (1) expressing 3y in terms of x by adding 2x to both sides
3y = - 7 + 2x
Substitute 3y = - 7 + 2x into (2)
5x - 7 + 2x = 28
7x - 7 = 28 ( add 7 to both sides )
7x = 35 ( divide both sides by 7 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (2)
5(5) + 3y = 28
25 + 3y = 28 ( subtract 25 from both sides )
3y = 3 ( divide both sides by 3 )
y = 1
solution is (5, 1 )
Answer:
-(3y-2x= -7)
3y+5x= 28
-3y+2x= 7
3y+5x= 28
7x=35
7x/7= 35/7
x=5
5(5)+3y= 28
25+3y=28
3y= 28-25
3y=3
3y/3=3/3
y= 1
3y-2x= -7
3(1) -2x= -7
3-2x= -7
-2x= -7-3
-2x= -10
-2x/-2=-10/-2
x= 5

5x+3y=28
5(5)+3(1)=28
