Area of a rectangle is expressed as the product of length and width. 

Area = l x w
Area = (3x+5)(x-2)
Area = 3x² - 6x + 5x - 10
Area = <span> 3x² - x - 10

Therefore, the correct answer is option D.</span>

A = L * W
A = (3x + 5)(x - 2)
A = 3x^2 - 6x + 5x - 10
A = 3x^2 - x - 10

Find the value of 7 Y if 3 bracket Y - 1 bracket is equal 21​
lawyer [7]

Answer:

7y = 56

Step-by-step explanation:

3(y - 1) = 21

Divide 3 on both sides:

y - 1 = 7

Add 1 to both sides:

y = 8

Multiply by 7 on both sides:

7y = 56

cis(x)=\cos x+i\sin x\\\\cis15^o=\cos15^o+i\sin15^o\\\\\cos15^o=\dfrac{\sqrt6+\sqrt2}{4};\ \sin15^o=\dfrac{\sqrt6-\sqrt2}{4}\\\\\text{therefore}\\\\7cis15^o=7\left(\cos15^o+i\sin15^o\right)=7\cos15^o+7i\sin15^o\\\\=7\left(\dfrac{\sqrt6+\sqrt2}{4}\right)+7\left(\dfrac{\sqrt6-\sqrt2}{4}\right)i

School A has 480 students and 16 classrooms. School B has 192 students and 12 classrooms.
boyakko [2]

Answer:96

Step-by-step explanation:

A; 480/16 = 30 students per classroom

B: 192/12 =16 students per classroom

we need x such that \frac{480-x}{16} = \frac{192+x}{12}

which means

(480-x )* 12 should be equal to (192+x) * 16

5,760 - 12x = 3,072+16x

5,760 - 3,072 = 12x + 16x

2,688 = 28x

x = 96

"eight times the difference of a number and three is sixty-four"?
morpeh [17]

Answer:

the number would be 11

Step-by-step explanation:

8    ·    x - 3       =      64

________                 _          (divide both sides by 8)

8                                 8

x - 3  =   8

+ 3         + 3

x  = 11

(check:

11 - 3 = 8

8 x 8 = 64 )
