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.

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 = 8

The 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

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
