A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram:


Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).


A = x(x − 4) − 0.5(8)(x − 4) − 4(8)

A = x(x − 4) − (8)(x − 4) − 4(8)

A = x(x − 4) + (8)(x − 4) + 4(8)

A = x(x − 4) + 0.5(8)(x − 4) + 4(8)

Answer:

d = - [tex]\frac{9}{13}[/tex]

Step-by-step explanation:

Given

13d + 8 = - 1 ( subtract 8 from both sides )

13d = - 9 ( divide both sides by 13 )

d = - [tex]\frac{9}{13}[/tex]

Answer:

Step-by-step explanation:

Given ,

13d + 8 = -1

=> 13d = -1 - 8

=> 13d = -9

[tex] = > d = \frac{ - 9}{13} [/tex]

Hence,

The value of d = -9/13 (Ans)

Answer:

Answer:

9.7cm

Step-by-step explanation

According to the sine rule;

a/sinA = c/sinC

8/sin55 = c/sin82

Cross multiply

csin55 = 8sin82

c(0.8192) = 8(0.9903)

c = 8(0.9903)/0.8192

c = 7.9221/0.8192

c = 9.67

Hence the value of c to the nearest tenth is 9.7cm

Answer:

Step-by-step explanation:

No, not quite. She's close.

The middle term (often called the linear term) is + which means that the absolute value of the factors must be plus.

(x + 5)(x - 3) is what should should think.

x + 5 = 0

x = - 5

x + 2 = 0

x = - 2

(x + 5)(x - 2)

x^2 - 2x + 5x - 10

x^2 + 3x - 10

Divide both sides by - 8, reversing the symbol as a result of dividing by a negative quantity.

6 > t , that is

t < 6

Answer:

Its 6.71

Step-by-step explanation:

Because using the formula, a^2+b^2=c2.

Answer:

x = 36

Step-by-step explanation:

Given

3(2x - 5) - 2x = 3(x + 7) ← distribute parenthesis on both sides

6x - 15 - 2x = 3x + 21

4x - 15 = 3x + 21 ( subtract 3x from both sides )

x - 15 = 21 ( add 15 to both sides )

x = 36

Answer:

y = 33.94 mm

x = 19.80 mm

Step-by-step explanation:

Because AC = CB, then ∠ABC = 45°

cos ∠ABC = 24/y

cos 45° = 0.7071 = 24/y

y = 33.94 mm

EF/BC = x/y

14/24 = x/33.94

24x = 475.16

x = 19.80 mm

Answer: THIS IS SO HARD!

Step-by-step explanation:

The required boiling temperature of platinum is 3,739 degrees Celsius.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.

Here,
a. Let's start by defining a variable for the boiling temperature of zinc, which we'll call z.

According to the problem statement, the boiling temperature of platinum is 199 more than four times the boiling temperature of zinc. In other words,

Boiling temperature of platinum = 4z + 199

So the expression that represents the boiling temperature of platinum in degrees Celsius is:

4z+199

b. The problem tells us that the boiling temperature of zinc is 907 degrees Celsius. So we can substitute this value for z in our expression:

4z+199 = 4(907)+199 = 3,739

Therefore, the boiling temperature of platinum is 3,739 degrees Celsius.

=502.65

Answer:

no

Step-by-step explanation:

Using the converse of Pythagoras' identity.

If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right.

longest side = 30 , then 30² = 900

20² + 23² = 400 + 529 = 929 ≠ 900

Then the triangle is not right.

Answer:

El orden es;

1) Cuadrilátero, 2) Rombo, 3) Paralelogramo, 4) Rectángulo, 5) Cuadrado

Step-by-step explanation:

Los términos dados son;

Cuadrilátero; Una forma con cuatro lados

Rombo; Un cuadrilátero con cuatro lados iguales

Cuadrado; Un cuadrilátero con cuatro lados iguales y cuatro ángulos iguales y dos lados paralelos opuestos

Rectángulo; Un cuadrilátero con cuatro ángulos rectos y dos lados paralelos opuestos

Paralelogramo; Un cuadrilátero con un par de lados paralelos opuestos

Observamos que todos los términos son cuadriláteros, por lo tanto, el cuadrilátero es el primer término

Por lo tanto, tenemos,

La primera forma es el cuadrilátero,

El cuadrilátero se transforma en un rombo (un cuadrilátero con lados iguales)

El ángulo del rombo se ajusta para dar un paralelogramo

El ángulo de paralelogramo dado cuatro ángulos iguales de 90 ° para dar un rectángulo

El rectángulo se ajusta para dar un cuadrado con todos los lados iguales
