Concept: Mathematical Derivation

We are given x^2 +6x+2x+12
Hence we simplify: x^2 + 8x +12
Now we factor: (x+2)(x+6)
By mathematical logic we now proved that the roots are x=-2 and x=-6

What is the value of x in the equation 4x+8y=40 when y=0.8

GREYUIT [131]

Substitute in 0.8 for y.

$4x+8y=40 \\ \\ 4x + 8(0.8) = 40 \\ \\ 4x + 6.5 = 40 \\ \\ 4x = 40 - 6.4 \\ \\ 4x = 33.6 \\ \\ x = 8.4 \\ \\$

The final result is: x = 8.4.

Answer:

D. 116

Step-by-step explanation:

Let the grasshoppers with a white marking be 2x.

Let the grasshoppers without a white marking be 3x.

2x + 3x = 290

5x = 290

x = 290 / 5

x = 58

The grasshoppers with a white marking

= 2x

= 2 ( 58 )

= 116

What is the landing strip’s area ?

attashe74 [19]

Answer:

Step-by-step explanation:

The perimeter P of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width ) , then

2l + 2(9) = 5364

2l + 18 = 5364 ( subtract 18 from both sides )

2l = 5346 ( divide both sides by 2 )

l = 2673

Then

A = lw = 2673 × 9 = 24057 m² → D
