Answer:
55.75
Step-by-step explanation:
find the area of 1 side using the base and height and divide that answer by 2
5x6=30 30 divided by 2=15
all sides are equal so each side is 15
the base you do the same thing.
base is 5, height is 4.3
4.3 x 5= 21.5
divide it by 2 10.75
side 1=15
side 2= 15
side 3=15
base 1= 10.75
add all together

8 3/5 = -4x + 5 3/5 ??
Solution??
Answer:
x=−3/4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
435=−4x+285
Step 2: Flip the equation.
−4x+285=435
Step 3: Subtract 28/5 from both sides.
−4x+285−285=435−285
−4x=3
Step 4: Divide both sides by -4.
−4x−4=3−4
x=−34
Answer:
as a decimal: [tex]x=-0.75[/tex]
as a fraction: [tex]x=-\frac{3}{4}[/tex]
Step-by-step explanation:
note: i'm going to convert the fractions to decimals because i prefer working with decimals rather than fractions :)
[tex]8\frac{3}{5}[/tex] as a decimal is [tex]8.6[/tex][tex]5\frac{3}{5}[/tex] as a decimal is [tex]5.6[/tex]the equation is now [tex]8.6=-4x+5.6[/tex]first, subtract 5.6 from both sides of the equation.
[tex]5.6[/tex] and [tex]-5.6[/tex] cancel each other out, leaving you with [tex]-4x+0[/tex] on the right side of the equation. it's not necessary to leave the [tex]0[/tex] in the equation, so just leave it as [tex]8.6=-4x[/tex]now subtract [tex]5.6[/tex] from the left side of the equation. [tex]8.6-5.6=3[/tex], therefore the equation is now [tex]3=-4x[/tex]then divide both sides of the equation by -4.
you are left with [tex]x[/tex] on the right side of the equation and [tex]-\frac{3}{4}[/tex] or [tex]-0.75[/tex] on the left side of the equation, aka [tex]x=-0.75[/tex] or [tex]x=-\frac{3}{4}[/tex]and that's it! the solution as a fraction is [tex]x=-\frac{3}{4}[/tex] and as a decimal is [tex]x=-0.75[/tex].
if you want to check the solution, just plug one of those values in for [tex]x[/tex] in the original equation. since i converted it all to decimals, i'll check my answer using [tex]-0.75[/tex] for [tex]x[/tex] in [tex]8.6=-4x+5.6[/tex].
first, plug in -0.75 for x.
[tex]8.6=-4x+5.6[/tex] ⇒ [tex]8.6=-4(-0.75)+5.6[/tex]begin simplifying by multiplying -4 and -0.75.
[tex]-4(-0.75) = 3[/tex][tex]8.6=3+5.6[/tex]add 3 and 5.6.
[tex]3+5.6=8.6[/tex][tex]8.6=8.6[/tex]since both sides of the equation are equal, that means your [tex]x[/tex] value is correct and therefore a solution to the equation!! :)

B
AC =
in.
Answer:
AC = 16 in.
Step-by-step explanation:
AD = CD = 10 in.
BD = 6 in.
AC = 2(AB) = ?
Apply pythagorean theorem to find AB
AB² = AD² - BD²
Substitute
AB² = 10² - 6²
AB² = 64
AB = √64
AB = 8
Therefore:
AC = 2(AB) = 2(8)
AC = 16 in.

Find the equation of the parabola whose vertex is the origin and whose directrix is x = -4
Try this option:
1) if V(0;0) and x= -4, then common view of the required equiation is:
(y-k)²=4p(x-h), where focus is in (h-p;k), the vertex is in (h;k), the directrix is x=h+p, p<0 and y=k is simmetry axis;
2) if the V(0;0), then h=k=0 and the required equiation is:
y²=4px;
3) if the directrix equation is x=h+p, where h=0, then p= -4 (according to the condition the directrix equation is x= -4), then the required equation is:
y²= -16x
answer: y²= -16x

The graph of f(x) = x2 was transformed to create a graph g(x) =f(x)+2.
Which statement about the graphs is true?
The vertex of the graph of g is 2 units above the vertex of the graph of f.
The vertex of the graph of g is 3 units to the right of the vertex of the graph of f.
The vertex of the graph of g is 2 units below the vertex of the graph of f.
The vertex of the graph of g is 2 units to the left of the vertex of the graph of f.
Answer:
The vertex of the graph of g is 2 units above the vertex of the graph of f.
Step-by-step explanation:
The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x). Then the correct option is A.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The graph of f(x) = x² was transformed to create a graph g(x) =f(x)+2.
Then the g(x) will be
g(x) = x² + 2
We know that the graph of the g(x) shifted to 2 units upward because we added 2 in the function.
The graph is shown.
The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x).
Thus, the correct option is A.

A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 25 feet more than the length of the shortest side. Find the dimensions if the perimeter is 157 feet
What is the length of the shortest side?
What is the length of the second side?
What is the length of the third side?
Answer:
shortest: 33 feet
second: 66 feet
third: 58 feet
Step-by-step explanation:
s = shortest side (33)
2s = second side (66)
25 + s = third side (58)
157 = s + 2s + 25 + s
157 = 4s + 25
4s = 132
s = 33
