Answer:x<1

Step-by-step explanation:

The expression (x+6)² is simplified as x²+12x+36.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

A) (3x-2)(x+5)

= 3x²-2x+15x-10

= 3x²+13x-10

B) (3x-8)(3x+8)

= (3x)²-8²

= 9x²-64

C) 5x(x-1)(x+7)

= (5x²-5x)(x+7)

= 5x²(x+7)-5x(x+7)

= 5x³+35x²-5x²-35x

= 5x³+30x²-35x

D) (x+6)²

= x²+12x+36

E) (x-2)(x-8)

= x(x-8)-2(x-8)

= x²-8x-2x+16

= x²-10x+16

So, A→2, B→5, C→1, D→3, E→4

Therefore, the expression (x+6)² is simplified as x²+12x+36.

Step-by-step explanation:

uhhhh the answer is -9 I think

Given:

A square base pyramid whose base length is 10 in. and height of triangular surface is 4 in.

To find:

The surface area of the pyramid to the nearest whole number.

Solution:

A square base pyramid contains square base with edge 10 in. and 4 congruent triangles with base 10 in. and height 4 in.

Area of a square is

[tex]A_1=(edge)^2[/tex]

[tex]A_1=(10)^2[/tex]

[tex]A_1=100[/tex]

So, area of square base is 100 sq. in.

Area of a triangle is

[tex]A_2=\dfrac{1}{2}\times base\times height[/tex]

[tex]A_2=\dfrac{1}{2}\times 10\times 4[/tex]

[tex]A_2=20[/tex]

So, area of each triangular surface is 20 sq. in.

Now, the total surface area of the pyramid is

Total area = Area of square base + Area of 4 congruent triangles.

[tex]A=A_1+4\times A_2[/tex]

[tex]A=100+4\times 20[/tex]

[tex]A=100+80[/tex]

[tex]A=180[/tex]

Therefore, the area of the pyramid is 180 sq. in.

Let Cesar's, Carmen's and Dalila's amount be represented by x, y and z respectfully.

Since they're money sum up to $95.34, the first expression will be;

x+y+z=95.34

Carmen_y_ is $12.12 less than cesar_x, so the equation will be ;

y=x-12.12

Cesar_x_raised $35more than Dalila_z. So the equation will be;

x=z+35

making z the subject, z=x-35 .

Substituting the Second equation into the first one, we get;

x+x-12.12+z=95.34

Subtracting the third equation into the new equation we get;

x+x-12.12+x-35=95.34

Simplifying, we get 3x- 47.12= 95.34.

3x=142.46

Answer:

x= 12

Step-by-step explanation:

First, we can note that the angles in a pentagon add up to 540°

We can, using the image below, conclude that angles a+b+c+d+f=540

Furthermore, a is on a straight line with 7x+4, and so on, so

180-(7x+4)= a

176-7x=a

180-(4x+1) = b

179-4x = b

180-(9x-6) = c

186 - 9x = c

180 - (4x+9) = d

171 - 4x = d

180 - (5x+4) = f

176 - 5x = f

a+b+c+d+f = 540

176-7x + 179-4x + 186 - 9x + 171 - 4x + 176 - 5x = 540

888 - 29x = 540

348 = 29x

x = 12

Answer:

  30% increase

Step-by-step explanation:

The percentage change can be computed from ...

  percent change = ((new value)/(old value) -1) × 100%

  = (70798.91/54460.7 -1) × 100% = (1.30 -1) × 100%

  = 30%

Answer:

It's D. 5

Step-by-step explanation:

A^2 + B^2 = C^2

The third length of the right triangle is 5 units. Then the correct option is D.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

We have

P = a

B = 12

H = 13

Then

13² = a² + 12²

169 = a² + 144

  a² = 169 – 144

  a² = 25

    a = 5

Then the correct option is D.

Answer:

The first option

Step-by-step explanation:

The equation of g(x) is g(x) = [tex]10^{3 - x[/tex]

Option A is the correct answer.

It is the movement of the shape in the left, right, up, and down directions.

The translated shape will have the same shape and size.

There is a positive value when translated to the right and up.

There is a negative value when translated to the left and down.

We have,

From the graph, we see that,

The coordinates in the line g(x) are (5, 100) and (4, 10).

Now,

g(x) = [tex]10^{x - 3[/tex] ______(1)

Substituting (5, 100) and (4, 10) in (1)

We get,

g(5) = [tex]10^{5 - 3[/tex] = 100

g(4) = [tex]10^{4 - 3[/tex] = 10

This is true.

Thus,

The equation of g(x) is g(x) = [tex]10^{3 - x[/tex]
