melamori03 [73]

(2x + 3) • (x + 3)

2x • x = 2x^2

2x • 3 = 6x

3 • x = 3x

3 • 3 = 9

6x and 3x combine to get 9x, which when all written out is equal to your original trinomial.

Help me on calculating the area of the shaded part

Ymorist [56]

Answer:

$1051 .55 {mm}^{2}$

Step-by-step explanation:

Find the area of the square - area of 4 sectors

We'll use the formula to find one sector area

$a = \frac{1}{2} \times {r}^{2} \times x$

where r is the radius of one sector and x is the angle in radians

Since each angle is in a square, the angle of the sectors is 90 degrees.

Convert degrees to radians

$90 = \frac{1}{2} \pi \: rad$

The radius of one sector is given by 70mm/2=35mm

One sector area:

$\frac{1}{2} \times {35}^{2} \times \frac{1}{2} \pi = 306.25\pi$

Area of all 4 sectors:

$4 \times 306.25\pi = 1225\pi$

Area of the square:

$70 \times 70 = 4900$

Hence, Area of square - 4 Sectors:

$4900 - 1225\pi = 1051.55 {mm}^{2} (2dp)$
