Step-by-step explanation:
x*x=x^2
x*9=9x
x*3=3x
9x+3x=12x
9x3=27
x^2+12x+27
Answer:
C
Step-by-step explanation:
To solve use the FOIL method, First, Outside, Inside, Last. This means to multiply the first terms, the ones on the outsides, the ones on the insides, and finally the last ones.
First, multiply x*x= [tex]x^{2}[/tex]
Then, multiply x*3= 3x
Next, multiply 9*x= 9x
Finally, multiply 9*3= 27
To simplify put all of the products together, [tex]x^{2}[/tex]+3x+9x+27, then add like terms [tex]x^{2}[/tex]+12x+27, so the answer is C.

A company manufactures acoustic guitars. The table shows the number of units that the company sold each month over a nine-month period beginning in January. Which equation best models the situation?
Answer:
i need this asap
Step-by-step explanation:
The equation that models the situation; [tex]y = 148.4 \sqrt {x-1} +154[/tex] Thus, option B is correct.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
A company manufactures acoustic guitars.
The table shows the number of units that the company sold each month over a nine-month period beginning in January, that is;
Month, x 1 2 3 4 5 6 7 8 9
Units, y 150 300 380 425 425 480 520 550 575
If we put x = 2
[tex]y = 148.4 \sqrt {2-1} +154\\\\y = 148.4 +154 = 302.4[/tex]
Y = 300 ( approx)
We can see that the equation that models the situation;
[tex]y = 148.4 \sqrt {x-1} +154[/tex]
Thus, option B is correct.

The HA theorem is a special case of the
Answer:
Option B.
Step-by-step explanation:
Two triangles can be congruent either by SSS or AAS or ASA or SAS postulates.
AAS is the case where two angles and one corresponding side of a triangle are equal.
For two right angled triangles, we already have one angle congruent as right angle. If another angle is congruent and hypotenuse equal, then the two triangles are congruent.
This directly follows from AAS theorem or AAS postulate

A gum ball has a radius that is 30mm. The radius of the gumballs spherical hollow core is 28mm. What is the volume of the gum ball if you do not include it's hollow core
Answer:
V = 21145.01 mm³
Step-by-step explanation:
Given that:
The radius of the gumball = 30 mm
The radius of the spherical hollow-core = 28 mm
Consider the radius of the gumball to be [tex]r_2[/tex] and the radius of the spherical hollow-core to be [tex]r_1[/tex]. Then;
The volume of the gumball can be determined by using the formula of a sphere.
[tex]V = \dfrac{4}{3}\pi (r_2^3 - r_1^3)[/tex]
[tex]V = \dfrac{4}{3} \times \pi \times (30^3 - 28^3)[/tex]
V = 21145.01 mm³

Answer:
C) the triangles are congruent
Step-by-step explanation:
Answer:
c. the triangles are congruent
Step-by-step explanation:
Both the triangles are right triangles which means the square thing at the bottom corner of the triangles are 90 degrees. So with this info, a triangle is 180 degrees, and one of the triangles already gave u one of the corners degrees so
90 + 59 + x =180
149 + x = 180
x = 31, so now the left triangle is solved. Now see the 118 degrees in the middle? A straight line is 180 degrees so with this in mind,
31 + 118 + x = 180
149 + x = 180
x = 31
The right triangle also has 31 and 90 as two of its angles, we don't need to calculate to know the last angle left is 59 like the left triangle. Therefore both triangles are congruent as they are the same.
