Answer:

6x^{2} +26x-20

Step-by-step explanation:

2(x+5)*(3x-2)=area

2(x+5)=2x+10

(2x+10)(3x-2)=

2x(3x)+10(3x)+2x(-2)+10(-2)

=6x^{2} +30x-4x-20

=6x^{2} +26x-20

Felicia places a rectangular rug that measures 10 feet by 11 feet in a triangular room with a base of 30 feet and height of 22 f
arsen [322]

Answer:

1. Area of rectangular rug is 110 ft^{2}

2. Area of triangular room is 330ft^{2}

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes, rectangle and triangle.

step one

let us start by solving for the area of the rectangular rug

given data

Area A =  ?

Length l =  11 ft

Width w=  10 ft

we know that the area of a rectangle is expressed as

Area=Length * Width

substituting our given data we have

Area= 11*10\\Area= 110 ft^{2}

step two

let us  solve for the area of the triangular room

given data

Area A =  ?

base b =  30 ft

height  h=  22 ft

we know that the area of a triangle is expressed as

Area= \frac{1}{2} *base* height\\

substituting our given data we have

Area= \frac{1}{2} * 30* 22\\Area=\frac{660}{2} \\Area= 330 ft^{2}

Solve for x. Round your answer to the nearest tenth. Type only the
solniwko [45]

Answer:

63.5

Step-by-step explanation:

using soh-cah-toa, you can determine that the x and the value given are sin(theta). Sin is opposite over hyp.

thus,

sin(theta) = 17 \div 19

theta =  {sin}^{ - 1} (17 \div 19)

once you solve that you get the angle x equals to 63.4746 which can be rounded to 63.5°

hope this helps!
