Here, we are given with ;
[tex]{:\implies \quad \sf (3x^{2}-7x)-(4x^{2}+6x)}[/tex]
Opening parentheses will yield;
[tex]{:\implies \quad \sf 3x^{2}-7x-4x^{2}-6x}[/tex]
Collecting like terms ;
[tex]{:\implies \quad \sf (3x^{2}-4x^{2})+(-7x-6x)}[/tex]

Work out the size of angle x.
Help!!!
Answers
x = 180 - 118 ( linear angles)
x = 62
62+62+y = 180
y = 56
Answer:
Step-by-step explanation:
Angle of a straight line = 180 degrees :)
So to find x you would do:
x = 180 - 118 = 62
Also the angle sum of a triangle = 180 degrees.
Since it is an isosceles triangle, the bottom two angles would be equal:
Angle sum of triangle = 180
x + x + y = 180
Since we know x = 62, substitute it into the above equation:
62 + 62 + y = 180
124 + y = 180
Subtract 124 from both sides to solve for y.
y = 180 - 124
y = 56

Answer:
The original price is $7926.83
Step-by-step explanation:
Step 1: Subtract the percent of the discount from the percent of the original cost:

Step 2: Convert the percent to a decimal.
82% = 0.82
Step 3: Solve for the original price.
[tex]\frac{0.82x}{0.82} = \frac{6500}{0.82}[/tex]

Which of the following expressions are equivalent to (x+4y)^2 check all that apply: A. x^2+8xy+16y^2 B. x^2+2xy+2y(x+2y) C. x^2+16y^2 D. x^2+4xy+4y(x+4y) Question 2. If the expression ax(2x+y-5) simplifies to 6x^2+3xy-15x, what is the value of a? Type only the numeric value into the box.
Answers
Given:
The expression is [tex](x+4y)^2[/tex].
The expression [tex]ax(2x+y-5)[/tex] simplifies to [tex]6x^2+3xy-15x[/tex].
To find:
The equivalent expression.
The value of a.
Solution:
The expression is
[tex](x+4y)^2[/tex]
Using [tex](a+b)^2=a^2+2ab+b^2[/tex], we get
[tex](x+4y)^2=x^2+2(x)(4y)+(4y)^2[/tex]
[tex](x+4y)^2=x^2+8xy+16y^2[/tex]
Therefore, the correct option is A.
The expression [tex]ax(2x+y-5)[/tex] simplifies to [tex]6x^2+3xy-15x[/tex]. So,
[tex]ax(2x+y-5)=6x^2+3xy-15x[/tex]
[tex]2ax^2+axy-5ax=6x^2+3xy-15x[/tex]
On comparing the coefficient of [tex]x^2[/tex],, we get
[tex]2a=6[/tex]
Divide both sides by 2.
[tex]a=3[/tex]
Therefore, the value of a is 3.

Answers
Melvin would have mowed 12/25 of the lawn of the when he takes his first break.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The total number of squares in the lawn = 100, 3/10 of the lawn = (3/10) * 100 = 30 squares
The number of squares already mowed = 18
Hence:
Fraction of the lawn Melvin have mowed when he takes his first break = (18 + 30) / 100 = 48/100 = 12/25
Melvin would have mowed 12/25 of the lawn of the when he takes his first break.

After watching baking shows on T. V. , Sanjay signs up for a cake-decorating class. To practice his new skills, he decorates a batch of cupcakes with sugar flowers. Sanjay puts 4 sugar flowers on each cupcake. In all, Sanjay puts 32 sugar flowers on the cupcakes. Which equation can you use to find the number of cupcakes c Sanjay decorates?
Answers
Answer:
4 sugar flowers for each cup
Total number of cups = 32
Generating The Equation
number of cupcakes (n) = (total cupcakes decorated)/( number of sugar flowers for each cup)n = 32/4n = 8The equation that can be use to determine the number of cupcakes c Tucker decorates will be 4n = 32.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that 4 sugar flowers for each cup
Total number of cups = 32
Generating The Equation;
The number of cupcakes (n) = (total cupcakes decorated)/( number of sugar flowers for each cup)
n = 32/4
n = 8
