Please I need help.

Answer:

XZ = 26.7

ZY = 11.7

Area = 140.4 sq inches

Step-by-step explanation:

m∠Z = 180-(26+90) = 64°

to get XZ you can use the law of sines:

sin 90°/XZ = sin 64°/24

1/XZ = sin(64°)

cross-multiply to get:

XZ·sin(64°) = 24

XZ = 24/sin(64°)

XZ = 26.7

to get ZY you can use the law of sines again:

sin 64°/24 = sin 26°/ZY

cross-multiply to get:

ZY·sin(64°) = 24·sin(26°)

ZY = 24·sin(26°) ÷ sin(64°)

ZY = 11.7

Area = 1/2(11.7)(24)

= 12(11.7)

= 140.4 sq inches

Rewrite each expression as a polynomial in standard form: (2x^2 − x^3 − 9x +1) − (x^3 +7x − 3x^2 +1)

Vitek1552 [10]

Answer:

Polynomial in standard form will be $-2x^3+5x^2-16x$

Step-by-step explanation:

We have given polynomial $2x^2-x^3-9x+1-(x^3+7x-3x^2+1)$

We have to write this polynomial in standard form

For writing in standard form we have to first subtract the polynomial and then rearrange the order

So $2x^2-x^3-9x+1-(x^3+7x-3x^2+1)=2x^2-x^3-9x+1-x^3-7x+3x^2-1=-2x^3+5x^2-16x$

So polynomial in standard form will be $-2x^3+5x^2-16x$
