No, because a scalene triangle has to have all sides that are different lengths. 2 sides being 13 inches would mean that the triangle has 2 sides that are equal, making it an isosceles triangle.
Answer:
no
Step-by-step explanation:
A triangle is scalene when its sides have three different lengths. Your triangle has two sides with the same measure, so it is isosceles, not scalene.

A square patio has a perimeter of (16x + 12) feet. What is the length of the patio?
Solution:
Note that:
Squares always have equal sides and angles.Perimeter of square patio: (16x + 12) ft.Factorize the perimeter.
16x + 12=> 4(4x + 3) ft.Find the length of the patio.
4(4x + 3)/4=> 4x + 3 ft.The length of the square patio is 4x + 3 ft.

whats the answer to 8/9 divided by 3/8
Answer:
[tex]\frac{64}{27}[/tex]
Step-by-step explanation:
We can use the "keep-change-flip" method to divide fractions
Keep: [tex]\frac{8}{9}/\frac{3}{8}[/tex]
Change: [tex]\frac{8}{9}*\frac{3}{8}[/tex]
Flip: [tex]\frac{8}{9}*\frac{8}{3}[/tex]
Now we can solve by multiplying across:
[tex]\frac{8}{9}*\frac{8}{3} =\frac{8*8}{9*3} =\frac{64}{27}[/tex]
Answer:
2 10/27
Step-by-step explanation:
8/9 / 3/8 = 8x8 / 9 x 3 = 64/27
64/27 = 2 10/27
50 pencils cost €7 . how much would 5 pencils cost
Answer:
5 pencils will cost €0.7
Step-by-step explanation:
We can set up a proportion to solve. We will have the cost on the top and the number of pencils on the bottom. I will have 50 pencils on the left, and 5 pencils on the right.
[tex]\frac{7}{50}=\frac{x}{5}[/tex]
Now we will cross multiply.
7 * 5 = 50 * x
35 = 50x
Divide both sides of the equation by 50.
0.7 = x
x = 0.7
5 pencils will cost €0.7

Two angles are supplementary. The measure of one angle
is 16 more than two times the measure of the other
angle. How many degrees are in each angle?
Answer:
The angles are 54 2/3 degrees and 115 1/3 degrees
Step-by-step explanation:
make an equation for the angles x being one angle and y being the other
16+ 2x =y
Supplementary angles add to 180
x + y = 180
Fill in y with the first equation
x + 16 +2x =180
simplify
3x +16 =180
subtract 16 from both sides
3x = 164
divide both sides by 3
x = 54 2/3
Insert the value of x into the first equation then simplify
16 + 2(54 2/3) =y
16 + 109 1/3 =y
115 1/3 =y

Find the inverse of the rational function
F(x)= 2x/x+3, x≠-3
as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.
[tex]\stackrel{f(x)}{y}~~ = ~~\cfrac{2x}{x+3}\implies \stackrel{\textit{quick switcheroo}}{x~~ = ~~\cfrac{2y}{y+3}}\implies xy+3x=2y\implies xy-2y+3x=0 \\\\\\ xy-2y=-3x\implies \stackrel{\textit{common factoring}}{y(x-2)=-3x}\implies y=\cfrac{-3x}{x-2}\implies \stackrel{f^{-1}(x)}{y}=\cfrac{3x}{2-x}[/tex]

Two angles of a quadrilateral measure 219° and 24°. The other two angles are in a ratio of 2:11. What are the measures of those two angles?
Answer: 18 and 99 degrees
Step-by-step explanation:
The sum of the measures of the other 2 angles is 360 - 219 - 24 = 117 degrees.
So the other two angles measure (2/13)(117)=18 degrees and (11/13)(117)=99 degrees

Triangle A BC is similar to triangle DEF. What are the lengths of sides DF and EF?
Answer:
DF = 4
EF = 1.6
Step-by-step explanation:
The scale factor is 1.25 because 5(big shape) ÷ 4(small shape) is 1.25.
To find EF, 2÷1.25 = 1.6
Which function has a vertex at (2, -9)?
O f(x) = -(x - 3)2
O f(x) = (x + 8)2
O f(x) = (x - 5)(x + 1)
f(x) = -(x - 1)(x - 5)
The function [tex]f(x)=\left(x-5\right)\left(x+1\right)[/tex] has a vertex at (2, -9).
Quadratic functionThe quadratic function can be represented by a quadratic equation in the Standard form: [tex]ax^2+bx+c[/tex] where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero ([tex]a\neq 0[/tex]) and the degree of the function must be equal to 2.
For solving this question, you should find the vertex of quadratic equation (h,k). Where, [tex]h=-\frac{b}{2a}[/tex] . On the other hand, the value of the k-coordinate will be found when you replace the value of h in the equation of your question.
1. [tex]f(x)=-(x-3)^2[/tex]
Write this equation in Standard form:
[tex]f(x)=-(x^2-6x+9)\\ \\ f(x)=-x^2+6x-9[/tex]
Find h, using the formula [tex]h=-\frac{b}{2a}[/tex]
[tex]h=-\frac{b}{2a} =-\frac{6}{2*(-1)} =-\frac{6}{-2}=-(-3)=3[/tex]
Find k, replacing x for the value of h
[tex]-x^2+6x-9\\ \\ -(3)^2+6*3-9=-9+18-9=-18+18=0[/tex]
The vertex of quadratic equation is (3,0). Incorrect Option.
2. [tex]f(x)=(x+8)^2[/tex]
Write this equation in Standard form:
[tex]f(x)=x^2+16x+64[/tex]
Find h, using the formula [tex]h=-\frac{b}{2a}[/tex]
[tex]h=-\frac{b}{2a} =-\frac{16}{2*1} =-\frac{16}{2}=-8[/tex]
Find k, replacing x for the value of h
[tex]x^2+16x+64\\ \\ (-8)^2+16*(-8)+64=64-128+64=128-128=0[/tex]
The vertex of quadratic equation is (-8,0). Incorrect Option.
3. [tex]f(x)=\left(x-5\right)\left(x+1\right)[/tex]
Write this equation in Standard form:
[tex]f(x)=(x^2+x-5x-5)\\ \\ f(x)=(x^2-4x-5)[/tex]
Find h, using the formula [tex]h=-\frac{b}{2a}[/tex]
[tex]h=-\frac{b}{2a} =-\frac{-4}{2*1} =-\frac{-4}{2}=-(-2)=2[/tex]
Find k, replacing x for the value of h
[tex]x^2-4x-5\\ \\ 2^2-4*2-5=4-8-5=-4-5=-9[/tex]
The vertex of quadratic equation is (2,-9). Correct Option.
4. [tex]f(x)=-\left(x-1\right)\left(x-5\right)[/tex]
Write this equation in Standard form:
[tex]f(x)=-\left(x-1\right)\left(x-5\right)\\ \\ f(x)=-(x^2-5x-x+5)\\ \\ f(x)=-(x^2-6x+5)\\ \\ f(x)=-x^2+6x-5[/tex]
Find h, using the formula [tex]h=-\frac{b}{2a}[/tex]
[tex]h=-\frac{b}{2a} =-\frac{6}{2*(-1)} =-\frac{6}{-2}=-(-3)=3[/tex]
Find k, replacing x for the value of h
[tex]-x^2+6x-5\\ \\ -(3)^2+6*3-5=-9+18-5=18-14=4[/tex]

Answer:
x=16⁰
Step-by-step explanation:
I AM NOT QUITE SURE OF THE ANSWER, but they are vertically opposite angles which in turn means that they are equal.
so you can equate the two sums they have given.
3x-3 = 2x+13
Take the numerical terms onto the right hand side and the 'x-terms' to the left hand side.
3x-2x = 13+3
That would leave you with,

5/3
-5/3
Answer:
-5/3
Step-by-step explanation:
We have two points on the line ( 0,2) and ( 3, -3) so we can use the slope formula to find the slope
m = ( y2 -y1)/(x2-x1)
= ( -3 -2)/(3-0)
= -5/3
