x = 8

Step-by-step explanation:

3x - 15 + 7x = 65

10x - 15 = 65

10x = 80

x = 8

A 4 cm x 6 cm rectangle sits inside a circle with radius with 11 cm. What is the area of the shaded region?

Novosadov [1.4K]

Answer:

The area of the shaded region is $(121\pi -24)\ cm^{2}$

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the circle minus the area of the rectangle

$A=\pi r^{2} -bh$

we have

$r=11\ cm$

$b=4\ cm$

$h=6\ cm$

substitute the values

$A=\pi (11^{2}) -(4)(6)$

$A=(121\pi -24)\ cm^{2}$ ----> exact value of the shaded area

factor 12t2 + 70t + 72 a= 12(t+3) (t+2) b= 2(3t+4)(2t+9) c= 2(3t+ 9) (2t+4) d= (6t+8)(2t+9)

evablogger [386]

Answer:

Step-by-step explanation:

$12t^2+70t+72=2(6t^2+35t+36)=2(6t^2+27t+8t+36)\\\\=2[3t(2t+9)+4(2t+9)]=2(2t+9)(3t+4)$
