Step-by-step explanation:
Because it actually simplifies into a binomial 5x+11 by collecting like terms
[tex] \huge \boxed{\mathfrak{Answer} \downarrow}[/tex]
[tex]\huge \sf \: 3x + 11 + 2x[/tex]
The above expression will not become a trinomial because 3x + 11 + 2x will get simplified to -> 5x + 11 l, which is a binomial (an expression having 2 terms). To make it simpler, trinomials are formed if there are 2 or more variables or if the given variable is squared or cubed so that the expression cannot be easily simplified.

Answer:
9x - 5
Step-by-step explanation:
(4x – 6) + (5x + 1).
4x - 6 + 5x +1
9x - 5
Have a good day
Answer:
9x - 5
Step-by-step explanation:
To get the this answer you would combine like terms. 4x and 5x are like terms, so you would combine them and get 9x. -6 and 1 are like terms, so you would combine those and get -5.

Angel got a job at in-n-out burger. He works 20 hours a week and makes $15.75 an hour. How much will his
paycheck be after 2 weeks of work (before uncle sam takes away taxes
Multiply hours per week by hourly pay rate:
20 x $15.75 = $315.00 per week
Multiply by 2 weeks:
$315 x 2 = $630
After 2 weeks paycheck is $630
Answer:
630
Step-by-step explanation:
15.75 x 20 = 315
315 is how much Angel makes in one week
315 x 2 = 630
630 is how much he will make in two weeks
The 2 signifies how many weeks have been worked
A regular square-based pyramid has a surface area of 33 m2. If its triangular faces have an area of 6 m2, what is the length of the base of the pyramid?
Answer:
First we can do 33 time 6
Step-by-step explanation:
The length of the base of the pyramid is 3 meters.
What is a square pyramid?A pyramid is a polyhedron that has a base and 3 or greater triangular faces that meet at a point above the base. A square pyramid is a pyramid with a square base, four triangular sides, five vertices, and eight edges.
For the given situation,
The surface area of the pyramid = 33 m^2
Area of triangular faces = 6 m^2
Let the base of the pyramid be b and the height be h.
The formula of area of triangle is
[tex]A = \frac{1}{2}(b)(h)[/tex]
⇒ [tex]6 = \frac{1}{2}(b)(h)[/tex]
⇒ [tex]6(2) = (b)(h)[/tex]
⇒ [tex]12 = (b)(h)[/tex]
The formula of surface area of square pyramid is
[tex]SA = b^{2}+2bh[/tex]
⇒ [tex]33=b^{2} +2(12)[/tex]
⇒ [tex]33-24=b^{2}[/tex]
⇒ [tex]b=\sqrt{9}[/tex]
⇒ [tex]b=3[/tex]
Hence we can conclude that the length of the base of the pyramid is 3 meters.

How do you solve this?
Answer:
f(- 10) = 74
Step-by-step explanation:
To find f(- 10) , substitute n = - 10 into f(n) , that is
f(- 10) = - 7(- 10) + 4 = 70 + 4 = 74
Hello there!
We are given a function below:
[tex] \displaystyle \large{f(n) = - 7n + 4}[/tex]
To find f(-10), substitute n = -10.
[tex] \displaystyle \large{f( - 10) = - 7( - 10) + 4}[/tex]
Evaluate the f(-10)
[tex] \displaystyle \large{f( - 10) = 70 + 4}[/tex]
Recall
Negative × Negative = PositiveTherefore,
[tex] \displaystyle \large{f( - 10) = 74}[/tex]
f(-10) = 74

the perimeter of a rectangular tray is 60in the length of the tray is double the width of a tray determine the dimensions of the rectangular tray
Answer:
Step-by-step explanation:
Width = w
Length = double the width = 2*w = 2w
Perimeter of rectangular tray = 60 in
2*(length + width) = 60
2*( 2w + w) = 60
2*3w = 60
6w = 60
Divide both sides by 6
w = 60/6
w = 10 in
length =2w = 2*10 = 20
length = 20 in
Width = 10 in

Oh and made 60% of the shots he attempted during his hockey practice he made 18 shots how many shots did Owen attempt during his hockey practice
Answer:
Owen attempted a total of 30 shots.
Step-by-step explanation:
Let's Owen's total number of attempted shots be S.
He made 60% of his total shots, which is 18. In other words, 60% of S is 18:
[tex]0.6S = 18[/tex]
Solve for S:
[tex]\displaystyle S = \frac{18}{0.6} = 30[/tex]
In conclusion, Owen attempted a total of 30 shots.

Find the area for all of these numbers
Answer:
The Answer is 29cm
Step-by-step explanation:
The area of this shape is made from two shapes.
Shape one is a rectangle with the dimensions 2cm by 4cm
2x4 = 8
So the area of rectangle 1 is 8
The other rectangle has the dimensions 4cm by 7cm
Because you have to account for the other triangle not being there (solved)
4x7 = 21
21+8

On a map, 1 inch equals 15.4 miles. If two cities are 3.5 inches apart on the map, how far are they actually apart?
Answer:
They are actually 53.9 miles away.
Step-by-step explanation:
1 in = 15.4 mi
Set up an equation:
Variable x = number of miles
1/15.4 = 3.5/x
Cross multiply:
1 × x = 15.4 × 3.5
