Answer:
x^2-5x + 6
Step-by-step explanation:
Here, we want to expand the given expressions
To do this, we multiply each term in the first bracket with each term in the second
We then proceed to collect like terms
We have this as;
x(x-3) - 2(x-3)
= x^2 - 3x -2x + 6
= x^2 -5x + 6
7 times the sum of a number and 4 is the same as 8 decreased by 3 times a number
7(x4) = 8-x
x= -2
your first step would be to move your 3x to the other side of the equation by adding 3x to both sides after this your equation should look as follows: 7(4+x)+3x=8 2nd: you should distribute your 7 to the numbers inside of the parentheses and combine like terms to get 10x+28=8 then you move your 28 to the other side by subtracting 28 and you will get 10x=-20 divide by ten to get the answer which is x=-2
Edit: Sorry for the answer before. I realised my mistake.

Which kind of triangle exists if the side measures are 3, 9, and 10?
i thought the answer was acute but my teacher marked it wrong and told me the correct answer was obtuse could someone explain why it would be obtuse?
Step-by-step explanation:
There is a rule that if c^2 > a^2 + b^2, then it is an obtuse triangle.
*c is the longest side
I attached more information on it below.

Step-by-step explanation:
h(x) = x^2 + 2 - x
g(x) = 4x + 5
find (h - g) (x/3)
Answer:
x^2 - 15x - 27
---------------------- (Answer C)
9
Step-by-step explanation:
(h - g)(x) is the difference between funcions h and g. Subtract g(x) from h(x) as follows:
x^2 + 2 - x
-(4x + 5)
-------------------
x^2 - 5x - 3 = (h - g)(x)
To find (h - g)(x/3), substitute x/3 for x in x^2 - 5x - 3 = (h - g)(x), obtaining:
(x/3)^2 - 5(x/3) - 3
We must expand this and then combine like terms:
x^2/9 - (5/3)x - 3
The LCD of these three terms is 9. The first term stays as is. The second term becomes (15/9)x. The third term becomes 27/9.
Combining these three terms, all with denominator 9, we get:
x^2 - 15x - 27
----------------------
9
This matches Answer C.

∠FEDstart color #1fab54, angle, F, E, D, end color #1fab54 and \blueD{\angle{x}}∠xstart color #11accd, angle, x, end color #11accd combine to form \angle{AED}∠AEDangle, A, E, D, which is a vertical angle with \goldD{\angle CEB}∠CEBstart color #e07d10, angle, C, E, B, end color #e07d10 because is opposite from \goldD{\angle CEB}∠CEBstart color #e07d10, angle, C, E, B, end color #e07d10.
Vertical angles are congruent, so \greenD{\angle{FED}} +\blueD{\angle{x}} = \goldD{\angle CEB}∠FED+∠x=∠CEBstart color #1fab54, angle, F, E, D, end color #1fab54, plus, start color #11accd, angle, x, end color #11accd, equals, start color #e07d10, angle, C, E, B, end color #e07d10.

Model the following problem with a quadratic equation. Then solve.
Find the length of a side of a square with an area of 180 ft^2.
Model the problem with a quadratic equation. Let x be the length of a side of the square.
Answer &
Step-by-step explanation:
area = length(width) = x(x) = x²
180 = x²
x² - 180 (quadratic equation)
Solve:
✓180 = ✓36✓5 = 6✓5 ≈ 13.42 ft = x
Answer:
[tex]x=6\sqrt{5}[/tex]
Step-by-step explanation:
1) A = s²
180 ft² = x²
180 = x²
x = x² -180
x²-180 =0
11) x² - 180 = 0
x² =180
x=[tex]\sqrt{36.5}[/tex]
x=[tex]6\sqrt{5}[/tex]

Write the equation of the line that passes through the points (4,7) and (8,6). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
y - 7 = [tex]-\frac{1}{4}[/tex] (x - 4)
Step-by-step explanation:
Find Slope: m = [tex]\frac{y_{2-}y_{1} }{x_{2-}x_{1} }[/tex]
m = [tex]\frac{6-(7)}{8-(4)}[/tex]
m = [tex]\frac{-1}{4}[/tex]
Point Slope Form: y - [tex]y_{1}[/tex] = m ( x - [tex]x_{1}[/tex] )
y - 7 = [tex]-\frac{1}{4}[/tex] (x - 4)
Kay's Dessert Shop bakes cookies. The ratio of chocolate chip to sugar cookies baked is always 5 to 2. If she bakes 210 cookies in one day, how many were sugar cookies? 50 points
Answer: 60
Step-by-step explanation:
Given
The ratio of chocolate chip to sugar cookies is 5:2
If she bakes 210 cookies in one day
Suppose she baked x amount of chocolate chips on that day
So, we can write
[tex]\Rightarrow x=\dfrac{2}{5+2}\times 210\\\\\Rightarrow x=\dfrac{2}{7}\times 210=60[/tex]
There were 60 sugar cookies on that day

Solve this inequality for x: - 3(x + 3) > 30
Answer:
x<-13
Step-by-step explanation:
−3(x+3)>30
Divide both sides by −3. Since −3 is negative, the inequality direction has changed.
x+3<30/-3
Divide 30 by −3 to get −10.
x+3<−10
Subtract 3 from both sides.
x<−10−3
Subtract 3 from −10 to get −13.
x<−13

Which rational exponent represents a square root?
А. 1/3
B. 1/2
C. 3/2
D. 1/4
Wich graph matches the equition y=-6x+3
Answer:
Option 1
Step-by-step explanation:
(I have limited time so am putting the explanation in numbers)
y = -6x(Slope) + 3(y-int.)
Find x
3 + -6x = y
-3 -3
-----------------
-6x=y-3
-6x/6 = y - 3/6
x = y - 3/ 6
The closest graph to this would be the first one.
Hope this helps :)
Answer:
Option 1
Step-by-step explanation:
-6 is the slope, another way this slope can be written is rise over run, or [tex]\frac{-6}{1}[/tex].
Because the y value is decreasing the slope is negative. Also, 3 is the
y-intercept, meaning it crosses the y axis on the graph. Put this together and it shows option 1 is correct
