Multiply the polynomials. (x2 – 4) (x2 + 3x – 5)

tiny-mole [99]

Answer:

$\boxed{ \bold{ \boxed{ \sf{ {x}^{4} + 3 {x}^{3} - 9 {x}^{2} - 12x + 20}}}}$

Step-by-step explanation:

$\sf{( {x}^{2} - 4)( {x}^{2} + 3x - 5)}$

Use distributive property

$\dashrightarrow{ \sf{ {x}^{2} ( {x}^{2} + 3x - 5) - 4( {x}^{2} + 3x - 5)}}$

$\dashrightarrow{ \sf{ {x}^{4} + 3 {x}^{3} - 5 {x}^{2} - 4 {x}^{2} - 12x + 20}}$

Collect like terms

$\dashrightarrow{ \sf{ {x}^{4} +3 {x}^{3} - 9 {x}^{2} - 12x + 20}}$

Hope I helped!

PLS HELP. this is due soon, only answer if you actually know it; no guessing for points please

OLga [1]

Answer:

102

Step-by-step explanation:

x = 180 - (4x - 2) - 78

x = 180 - 4x + 2 -78

5x = 180 + 2 - 78

5x = 104

x = $20\frac{4}{5}$ .

So, angle UTW is 4 * $20\frac{4}{5}$ - 2 + $20\frac{4}{5}$ = 5 * $20\frac{4}{5}$ - 2 = 104 - 2 = 102
