1) the answer to the radical is x^3+6x^2+12x+ 8
2) simplify this : x^3+6x^2+12x+ 8 + 3 = 27, into
3) this : x^3+6x^2+12x+ 11 = 27
4)Subtract 27 from both sides
x^3+6x^2+12x -16= 0
5) Use cubic formula.
x = 0.884499

What is the decimal multiplier to decrease by 78%?

torisob [31]

Answer:

0.22

Step-by-step explanation:

Let assume the number to be reduced be 100

Reducing it by 78% will be:

100 - ( 78% of 100 )

100 - (78/100)×100

100 - 0.78 × 100

100 - 78 = 22

Since the answer is 22. Hence,

22/100 will be the multiplier

0.22 × 100 = 22

Find the distance of (-7,-5) and (-3,4) round to the nearest tenth

Luba_88 [7]

Answer:

7.2 units

Step-by-step explanation:

Distance² = (Change in y)² + (Change in x)²

Distance² = (4 - -5)² + (-3 - -7)²

Distance² = 36 + 16

Distance² = 52

Distance = 7.211102551

Rounding off the answer to nearest tenth gives 7.2 units

What is the area of the rhombus?

IRINA_888 [86]

The area of rhombus is 24 square units.

Step-by-step explanation:

Given,

Length of one diagonal = p = 3+3 = 6 units

Length of other diagonal = q = 4+4 = 8 units

Area of rhombus = $\frac{pq}{2}$

Area of rhombus = $\frac{6*8}{2}$

Area of rhombus = $\frac{48}{2}$

Area of rhombus = 24 square units

The area of rhombus is 24 square units.
