(b) Each triangular part has an area that is greater than the area of each rectangular part.

(c) Each triangular part and each rectangular part represents 1/4 the area of one square

(d) Each rectangular part has an area that is greater than the area of each triangular part.

See attachment for squares

Answer:

(a) Each triangular part and each rectangular part represents 1/2 the area of one square.

Step-by-step explanation:

Given

See attachment

Required

Which statement is true

Before the division, the area of both squares is:

[tex]Area = l * w[/tex]

After the division:

The area of the triangle is:

[tex]Area = \frac{1}{2} * base * height[/tex]

[tex]A_1 = \frac{1}{2} * l * w[/tex]

Substitute Area for l * w

[tex]A_1 = \frac{1}{2} *Area[/tex]

This equals half the area of the square

The area of the rectangle is:

[tex]Area = length * width[/tex]

The length of the rectangle is now half the length of the original square.

So, we have:

[tex]A_2 = \frac{1}{2} l * w[/tex]

Substitute Area for l * w

[tex]A_2 = \frac{1}{2} *Area[/tex]

From the values of A1 and A2, we can conclude that (a) is true

Use FOIL to multiply.
(3x - 7)(x + 5)

Answers

3x^2-7x+15x-35
=3x^2+8x-35

Answer:

3x²+8x-35

Step-by-step explanation:

FOIL stands for:

First -> (3x-7)(x+5)

Outer -> (3x-7)(x+5)

Inner -> (3x-7)(x+5)

Last -> (3x-7)(x+5)

Following FOIL, we get:

(3x-7)(x+5)

(3x)(x)+(3x)(5)+(-7)(x)+(-7)(5)

3x²+15x-7x-35

3x²+8x-35

Therefore, the expanded form is 3x²+8x-35

Si quieren llegar a tiempo para tomar el tren, ¿Cuánto debe recorrer la caravana el último día? A) 18/29 B) 19/30 C) 20/31 D) 21/32

Answers

Answer:

B) 19/30

Step-by-step explanation:

Se deben recorrer 5km en total, en números fraccionarios se recorren:

1er día:

1200m = 1.2km = 6/5km

2do día:

1 + 2/3km = 5/3km

3er día:

1.5km = 3/2km

La suma da:

6/5km + 5/3km + 3/2km = 36/30km + 50/30km + 45/30km = 131/30km.

5km son 150/30km.

150/30km - 131/30km = 19/30 km

La respuesta es:

B) 19/30

At a candy store, Jordan bought 2 pounds of jelly beans and 3 pounds of gummy worms for $41. Meanwhile, Isabelle bought 2 pounds of jelly beans and 6 pounds of gummy worms for $68. How much does the candy cost?

Answers

Answer:

Cost of a pound of Jelly beans = x = $7

Cost of a pound of Gummy worms = y = $9

Step-by-step explanation:

Let us represent

Cost of a pound of Jelly beans = x

Cost of a pound of Gummy worms = y

At a candy store, Jordan bought 2 pounds of jelly beans and 3 pounds of gummy worms for $41.

2x + 3y = 41....... Equation 1

Meanwhile, Isabelle bought 2 pounds of jelly beans and 6 pounds of gummy worms for $68.

2x + 6y = 68...... Equation 2

Combining Equation 1 and 2 together

2x + 3y = 41....... Equation 1

2x + 6y = 68...... Equation 2

We Subtract Equation 1 from Equation 2, thereby eliminating x

3y = 27

y = 27/3

y = $9

Solving for x

2x + 3y = 41....... Equation 1

2x + 3(9) = 41

2x + 27 = 41

2x = 41 - 27

2x = 14

2x/2 = 14/2

x = $7

Therefore, the cost of each candy =

Cost of a pound of Jelly beans = x = $7

Cost of a pound of Gummy worms = y = $9
