-2x(x+3)-(x+1)(x-2)=
Answer:
[tex]-3x^{2}[/tex] -5x +2
Step-by-step explanation:
Just combine like terms and solve.
-2x^2+-6x - (x+1)(x-2)
Use foil on the second part
-2x^2-6x - x^2-x-2
Now combine like terms and you’d get your final answer
Beth has saved 60$ for a gaming system.This is 30% of the total amount she needs for gaming system.how much does the new gaming system cost?
Answer:

The lifetime for a certain brand of widgets is normally distributed. A random sample of 25 widgets is taken and a sample mean lifetime of 520 hours with a standard deviation of 50 hours. Before taking the sample, researchers claimed that the mean lifetime of a widget was more than 500 hours. 1. null hypothesis:
2. the alternative hypothesis:
3. explain what test will be used and why?
Answer:
1. H0: u = 500
2. H1: u <500
3. One sample t test
Step-by-step explanation:
1. The null hypothesis in this question would be
H0: u = 500
2. The alternative hypothesis would be
H1: u < 500
3. The test that we are going to be using is the one sample t test. This test is used to test hypothesis. It would make a comparison of h0 to the mean of the sample. Now we are using this here because the sample standard deviation was given

find degree measures of marked angles in fig 5.47
Answer:
50+P=125 exterior angle of the triangle is equal to the sum of two opposite interior angle
P=125-50=75°
q+125=180 linear pair
q=180-125=55°
r=q=55° vertically opposite angle
s+85=125 exterior angle of the triangle is equal to the sum of two opposite interior angle
s=125-85=40°
s+t=180 linear pair
t=180-40=140°
u=s=40° vertically opposite angle
w=65° vertically opposite angle
v+u+w=180 sum of interior angle of the triangle is 180
v+40+65=180
v=180-105=75°
x+65=180 linear pair
x=180-65=115°

Answer:-1 °F
Step-by-step explanation:
Answer:
-1°F

10AM = -15
11AM = -13
12AM = -11
1PM = -9
2PM = -7
3PM = -5
4PM = -3
5PM = -1
or 10AM to 5PM is 7 hours and 2*7 = 14, so them -15 + 14= -1

An equilateral triangle has a side length of 1.4x + 2 inches
. A regular hexagon has
a side length of 0.5x + 2 inches. The perimeters are equal. What is the side length
of the triangle? What is the side length of the hexagon? Show your work.
op
SOLUTION
Answer:
The Perimeter of an equilateral triangle = 1.4x+2+1.4x+2+1.4x+2
= 4.2x+6
The Perimeter of a regular hexagon = 0.5x+2+0.5x+2+0.5x+2+0.5x+2+0.5x+2+0.5x+2
= 3x+12
Given that the perimeters are equal
4.2x+6 = 3x+12
4.2x - 3x = 12-6
1.2x = 6
x = 6/1.2
x=5
The side length of the triangle = 1.4x+2
= 1.4 (5) +2
= 9 inches
The side length of hexagon = 0.5x+2
= 0.5(5) +2
= 4.5inches
