Answer:

B

Step-by-step explanation:

Given

(4x² - 3x - 4) - (3x² + 4x - 8) ← distribute by - 1

= 4x² - 3x - 4 - 3x² - 4x + 8 ← collect like terms

= x² - 7x + 4 → B

Step-by-step explanation:

(4 {x}^{2}  - 3x - 4) - (3 {x}^{2}  + 4x - 8) \\  \\  = 4 {x}^{2}  - 3x - 4 - 3 {x}^{2}  - 4x + 8 \\  \\  = 4 {x}^{2}  - 3 {x}^{2}  - 3x - 4x - 4 + 8 \\  \\  =  {x}^{2}  - 7x + 4

Thus option B is the correct answer.

Answer:

the missing value is 9.33.

Step-by-step explanation:

given,

length (l) = 3x+2

breadth (b) = 4

perimeter(P) = 68 cm

now,

P = 2(l+b)

or, 68 = 2× ( 3x+2+4)

or, 68 = 2× ( 3x+ 6)

or, 68 = 6x+12

or, 68 - 12= 6x

or, 56 = 6x

or, 6x = 56

or, x = 56/6

or, x = 9.33

Answer:

<h2>             18.3</h2>

Step-by-step explanation:

from cosines theorem:

t² = 11² + 14² - 2•11•14•cos87°

t² = 121 + 196 + 308•0.05236

t² = 333.12688

t = √333.12688

t = 18.2517... ≈ 18.3
