Answer:

c²(1 + 3d)

Step-by-step explanation:

The sum of square of c and d is;

c² + d

Twice the product of c and d is;

2c²d

Because c² + d is increased by 2c²d the algebraic expression becomes;

c² + d + 2c²d

c²(1 + 3d)

Are these correct? ILL MARK YOU BRAINLIEST

Oxana [17]

Answer:

Yes

Step-by-step explanation:

1) Cos 300 = Cos (360 - 60) = Cos 60 {Cos 360 - theta = Cos theta}

= 1/2

Sin 300 = Sin (360 - 60) = -Sin 60 = $\frac{-\sqrt{3}}{2}$

3) 3π/4 = 3*180/4 = 135

Cos 135 = Cos (90 + 45) = -Cos 45 = $\frac{-\sqrt{2}}{2}$

Sin 135 = Sin (90 + 45) = Sin 45 = $\frac{\sqrt{2}}{2}$

These two triangles are similar .Find side lengths a and b .The two figures are not drawn to scale

ziro4ka [17]

Answer:

a = 6, b = 22.5

Step-by-step explanation:

One triangle is 2.5 times bigger than the other.

9*2.5=22.5 which means b = 22.5

15/2.5=6 which means a = 6
