The area of the rectangle shown is 32x^2 + 12 If width can be represented by 4x, write an expression to represent the length of the rectangle
Answer:
L=(8x^2+3)/x
Step-by-step explanation:
The area of a rectangle is length time width.
A=LW
In this case,
A=32x^2+12
W=4x
Solve for L
L=A/W
Substitute
L=(32x^2+12)/4x
L=(8x^2+3)/x
X – 3 > 2?

Answer:
x= 20, y=95
Step-by-step explanation:
If you see the x angle, it makes 90 degree, and the straight line divides that angle into two. So by that;
x+25=45
x=20
Now if you add up all the angles on the straight line, it makes 180 degree,
by that,
x+25+y+40=180 (straight lines' angle=180 degree)
we now know that x=20, so now by adding that value, we get
20+25+y+40=180
y=180-40-25-20
y=180-85
y=95.

the base of a triangular field is 22m. The area of the field is 550m2 . find the height
Step-by-step explanation:
Area of triangular prism =1/2 ×base×height
550=1/2×22×h
h=550/11
h=50m
hope it helps.
Answer:
height = 50 m
Step-by-step explanation:
Area of a triangle = 1/2* base * height
550 = 1/2 * 22 * height
550 = 11 * height
therefore, 550/11 = height
therefore, height = 50 metres
The length of a rectangle is 2x-7 and the width is 3x+5. Describe the step you would need to take to find the area of the rectangle.
I would really appreciate it!
Answer:
[tex]A= 6x^2-11x-35[/tex]
Step-by-step explanation:
Given data
Length= 2x-7
Width= 3x+5.
Area= L*W
substitute
[tex]A= (2x-7)* (3x+5)[/tex]
Open bracket
[tex]A= 6x^2+10x-21x-35[/tex]
collect like terms
[tex]A= 6x^2-11x-35[/tex]
Hence the area is
[tex]A= 6x^2-11x-35[/tex]
Can someone please help me outt
Answer:
ASA
Step-by-step explanation:
We can see that the triangle has at least one similar side and one similar angle. We can also see that the triangles meet at a point, so they must have the same angle at that point where they connect. So that leads us to our answer being ASA since they have two similar angles and one similar side. This is the answer that I think is correct just by looking at the image. I haven't take this class since last year, so this is simply from memory. Correct me if I am wrong!
Which equation represents a nonlinear function?
O A. 7x - 3y = 0
O B. X = 12y - 4
O C. 9xy = 19
O D. X + 7 = 0
what is the value of x , if y = 2
in the given equation ;
5x + 2y = 9
Answer:
Solve the system of equations.
x = 1
y = 2
Step-by-step explanation:
Hope it is helpful....
[tex]5x + 2y = 9[/tex]
with given condition where y = 2.
Therefore, substitute the value of y in the equation.
[tex]5x + 2(2) = 9 \\ 5x + 4 = 9[/tex]
Solve the equation for x-term.[tex]5x = 9 - 4 \\ 5x = 5 \\ x = \frac{5}{5} \longrightarrow \frac{1}{1} \\ x = 1[/tex]
Check the answer by substituting both x-value and given y-value in the equation.[tex]5x + 2y = 9 \\ 5(1) + 2(2) = 9 \\ 5 + 4 = 9 \\ 9 = 9 \longrightarrow \bf{true} \: \green{ \checkmark}[/tex]
Hence, the value of x is 1.

3. (1) [tex]y=\frac{1}{4}x[/tex]
4. a) [tex]y=x+6[/tex] b) [tex]42[/tex]
Step-by-step explanation:
In a proportional relationship, y=2 when x=8, the following lines will show this relationship,
1. y = 1/4x
2. y = x - 6
4. y = 1/2x - 2
What is the equation of line?The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.
Given that,
The point,
x = 8 and y = 2
We have to check all the given options,
1. y = 1/4x
y = 1/4 × 8
y = 2
2. y = x - 6
= 8 - 6
y = 2
3. y = 4x
= 4 × 8
y = 32
4. y = 1/2x - 2
= 1/2 × 8 - 2
= 2
Hence, Option 1, 2, & 4 satisfies the given condition

The sum of the ages of a boy and his mother is 48. If the mother is three more than twice the boy’s age, find the difference in the ages of the boy and his mother.
Answer:
18 years
Step-by-step explanation:
let the boy's age my x and mother's age be y
x+y=48
y=3+2x which can also be written as 2x-y=-3
on solving both the equations,
you will get x=15 and y=33
so son's age is 15 years and mom's age is 33 years and the difference between their ages is 18

Which number line shows all the values of that make the inequality - 3x +1 < 7 true?
Answer:
D
Step-by-step explanation:
First, simplify the equation.
-3x+1<7
-3x<6
x>-2 (the sign flips because you are dividing by negative)
> means x is greater than -2 so the line will go towards the right.
Because the sign is >, the dot is open.
The number line C shows all the values for the inequality -3x + 1 < 7.
What is an inequality?'In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal.'
According to the given problem,
Given inequality = -3x + 1 < 7
⇒ -3x < 7 - 1
⇒ -3x < 6
⇒ -x < 2
⇒ x > -2
Interval notation of the values of x = ( -2 , ∝ )
Number line C graphs all the values of x, which is greater than -2 and extends up to infinity.
Hence, we can conclude number line C shows all the values of x in the interval (-2 , ∝).
