Answer:
If the 7 x 2 is in parenthesis then you would do the 7 x 2 first then do 14 by the power of 3. If there is no parenthesis and the power of 3 is hovering next to the 2 then you would do 2 to the power of 3 and then multiply that by 7.
Step-by-step explanation:
PEMDAS. Whatever is in parenthesis gets solved first, then exponents and so on and so forth.

2x+5y=0
3x-4y=23
solve the following simultaneous equation
Answer:
[tex]x = 5[/tex], [tex]y = -2[/tex]
Step-by-step explanation:
[tex]2x + 5y = 0[/tex]
[tex]3x - 4y = 23[/tex]
By using substitution:
[tex]2x + 5y = 0[/tex]
[tex]2x = -5y[/tex]
[tex]x = -\frac{5}{2}y[/tex]
[tex]3x - 4y = 23[/tex]
[tex]3 (-\frac{5}{2} y) - 4y = 23[/tex]
[tex]-\frac{23}{2} y = 23[/tex]
[tex]y = -2[/tex]
[tex]x = -\frac{5}{2} y[/tex]
[tex]x = -\frac{5}{2} (-2)[/tex]

What is 10,274 - 100,000
Answer:
_89,726
Step-by-step explanation:
This would be a negative answer in less you mean 100,000 - 10,274.
This would be negative because 10,000 per say can't subtract 100,000 in less it goes on the negative side.
But if you meant 100,0000-10,274 it is the same answer just with no nefative sign

expand and simplify x(x-4)(x-1)
Answer:
x^3 - 5x^2 +4x
Step-by-step explanation:
x(x-4)(x-1)
(x^2-4x)(x-1)
x^3-x^2-4x^2+4x
simplify
x^3-5x^2+4x
Answer:
Expand:
This is in its expanded form.
Simplify:
First do the x and the (x-4)
distribute the x
(x^2-4x)
Then FOIL or draw you grid and multiply out.
x^2 times x = x^3
x^2 times -1 = -x^2
-4x times x = -4x^2
-4x times -1 = 4x
Combine like terms.
x^3 + (-4x^2 -x^2) + 4x
Answer : x^3 - 5x^2 + 4x

What is the slope of a line parallel to the line whose equation is
5x – 3y = 18.
Fully simplify your answer.
Answer:
5/3, or 1.(6)
Step-by-step explanation:
find slope-intercept form
5x-3y=18
5x=3y+18
3y=5x-18
y=5/3x-6
slope is 5/3, or 1.(6)
The slope is 5/3 or 1.6.
What is a slope?It is the measure of the steepness of a line.
Given that
5x-3y = 18
Rearrange the equation
i.e. 5x-18 = 3y
y = (5/3)x - 6
The general form of the slope-intercept equation is
y = mx+c
By comparing the two equation, we get slope as
Slope of the line,m = 5/3 = 1.6
Hence, the slope of the given line is 1.6.

A triangular prism has a height of 12 cm. The triangular base is a right triangle whose side lengths are 3 cm, 4 cm, and 5 cm. What is the total surface area?
Answer:
The volume of the prism is 72 cubic cm.
Step-by-step explanation:
This we know because a triangle with sides of 3 units, 4 units, and 5 units must be a 3–4–5 right triangle, the catheti (“legs”) of which are 3 and 4 units. So the area of the base is
3 cm. * 4 cm. / 2 = 6 square cm.
Lastly, the volume of the prism is the base area multiplied by the height:
6 square cm. * 12 cm. = 72 cubic cm.

The formula is in a quadratic formula shape: [tex]y = ax^2+bx+c[/tex]
The function is negative since the value 'a' the coefficient of x^2 is negative meaning that the quadratic function is facing downards. If you don't get this explanation, take a look at the diagram I uploaded.
That means the highest point of the graph is its vertex.
But we must find where the vertex is at or the 't' value.
't' value at which vertex is = [tex]-\frac{b}{2a} =-\frac{16}{2*(-16)} =\frac{1}{2}[/tex]
Now plug this 't' value into h(t) to find the maximum height, and we will get 36 feet.

Find the measures of the numbered angles in rhombus ABCD .
look for all four measures numbered in the photo
Answer:
<1=54, <2=36, <3=90, <4=36
Step-by-step explanation:
in the rhombus shown, there are 4 congruent right triangles because the disgonals of a rhombus are perpendicular and the sides of a rhombus are congruent. We already know that the larger acute angles are all 54 degrees and we can use triangle sum to find that the smaller acute angles are all 36 degrees. Obviously the right angles are 90 degrees, so we can look at the picture and find the marked angles.
