1. Simplify .........​

Answer:

No

Step-by-step explanation:

21 = 3p - 5

Step 1 : Add 5 on both sides

21 + 5 = 3p

26 = 3p

3p = 26

Step 2 : Divide 3 on both sides

p = 26/3

Hence, the solution of the given equation is 26/3, not 9.

Answer:

Step-by-step explanation:

The equation of the line of fit and the data shows that the number of hats will be 48.

From the information, x games is won as y hats are sold. Therefore, the equation is given as:

y = 3.75x + 13.75

y = 3.75(9) + 13.75

y = 47.5

y = 48.

Therefore, the number of hats sold is 48.

The value of f(4) and 3[f(t)] if f(t) = 2t³ is 512 and 6t³ respectively.

To calculate the polynomial expression below, we use the technique below.

From the question,

Given:

To find f(4) we substitute 4 as the value of x in equation 1

To find 3[f(t)] we multiply equation 1 by 3

Hence, the value of f(4) and 3[f(t)] if f(t) = 2t³ is 512 and 6t³ respectively.

The area of the smallest side of the right triangle is 25 ft².

A triangle having two sides at an angle of 90 degrees is called the right-angle triangle.

Note:- The figure is missing in the question I am attaching the complete figure with the answer below for calculation.

Given that:-

The hypotenuse = 169 ft ²  = 13 ft

The side with area 144 ft²   = 12 ft

Using Pythagoras' identity to find the third side x ( smallest )

x² + 12² = 13²

x² + 144 = 169 ( subtract 144 from both sides )

x² = 25 ( take the square root of both sides )

x = 5

Thus the area of the smallest side will be calculated as:-

A =  5²

A =  25 ft²

Therefore the area of the smallest side of the right triangle is 25 ft².

La suma de dos números enteros negativos siempre será negativa. El signo de la suma de dos números enteros con signos diferentes dependera de cual tiene mayor valor absoluto.

La suma de dos números A y B se escribe como:

A + B.

Sí ambos números son negativos, los podemos escribir como:

A = -a

B = -b

Donde a y b son positivos.

Entonces la suma de esos dos nos dará:

(-a) + (-b) = -(a + b).

Es decir, el resultado de la suma es un número negativo.

Un ejemplo es sí tomamos:

A = -1

B = -4

(-1) + (-4) = -(1 + 4) = -5.

En este caso dependerá de que número tenga mayor valor absoluto.

Por ejemplo, sí usamos:

A = 2

B = -4

2 + (-4) = -2

El resultado es negativo, pues el número negativo tiene mayor valor absoluto.

Por otro lado, sí tenemos:

A = -2

B = 4

(-2) + 4 = 2

El resultado es positivo, pues el número positivo tiene mayor valor absoluto.

The measure of the three missing angles in the given rhombus are:

x = 122°

z = 58°

y = 122°

A rhombus is a quadrilateral with four interior angles. In a rhombus, the opposite angles are congruent while the adjacent angles are supplementary to each other.

x and 58° are adjacent angles and are therefore supplementary.

x = 180 - 58 = 122°

z = 58° (opposite angles)

y = x = 122° (opposite angles)
