Refer to the rectangle below. The length of the rectangle is x + 12. The width of the rectangle is x + 3.
Elis [28]

Answer:

x^2+15x+36

Step-by-step explanation:

The complete question is shown in the attachment.

The length of the rectangle is x + 12. The width of the rectangle is x + 3.

Recall that area of a rectangle is Length \times Width

In terms of x, the area is (x+12)(x+3)

Recall the distributive property of real numbers: (a+b)(c+d)=a(c+d)+b(c+d)

We apply this property to get:

(x+12)(x+3)=x(x+3)+12(x+3)

We expand again to get:

(x+12)(x+3)=x^2+3x+12x+36

We now simplify to obtain:

(x+12)(x+3)=x^2+15x+36

The area of the rectangle is x^2+15x+36

Can someone help with my homework?
USPshnik [31]

Step-by-step explanation:

To divide by a fraction, multiply by its reciprocal.

1) (m² / 9) / (n² / m)

(m² / 9) × (m / n²)

m³ / (9n²)

2) (4 / y) / (2 / (yx))

(4 / y) × (yx / 2)

2x

3) (x² / y) / (1 / y)

(x² / y) × (y / 1)

x²

4) (3 / b) / (9 / a²)

(3 / b) × (a² / 9)

a² / (3b)

5) (x² / 16) / (16 / y²)

(x² / 16) × (y² / 16)

x²y² / 256

The area of triangle DEF is 2137.5 cm²

Solution:

Given data:

Area of ABC = 38 cm²

Scale factor = 7.5

To find the area of DEF:

<em>Area of dilated image = Area of original image × (scale factor)²</em>

Area of DEF = 38 × (7.5)²

                    = 2137.5 cm²

Area of DEF = 2137.5 cm²

The area of triangle DEF is 2137.5 cm²
