# Area of painting = 20 × 16

# Area of combination = 25 × 20

.°. Area of frame = Area of combination - Area of painting

= (25×20)-(20×16)

=20 (25-16)

=20 × 9

$= 180 {cm}^{2}$

Find the value of X round to the nearest degree

sashaice [31]

Answer:

Step-by-step explanation:

to find the value of x use "sinerule"

sinx/13= Sin90/17

sinx = sin90×13/17

sinx= 14/17

sinx= 0.764705882

X= SIN^-1(0.764705882)

X = 49.888

X= 50

Corey wants to estimate the height of the statue of Stephen F. Austin in Angleton, Texas. He stands approximately 19.3 feet away

aniked [119]

The statute is about 80 feet tall

<h3>Similar triangles;</h3>

In order to get the height of the statute, we will need to get the base of the bigger triangle using the similarity theorem of triangles as shown:

B/19.3 = 19.3/5

5B = 372.49

B = 372.49/5

B = 74.498

<h3>Get the height of the status</h3>

The height of teh status = B + 5

Height of the status = 74.498 + 5

Height of the status = 79.498

Hence the statute is about 80 feet tall

7-3 Multiplying Binomials

Nataly [62]

Answer:

Step-by-step explanation:

Use FOIL method.First multiply (5x + 1) and (3x - 4). Then multiply (15x² - 17x - 4) by (x +2)

Volume of the rectangular prism = length *width * height

= (5x + 1) (3x -4)(x +2)

= [ 5x*3x + 5x*(-4) + 1*3x + 1*(-4) ] (x + 2)

= [15x² <u>- 20x + 3x</u> - 4] (x +2) {Combine like terms}

= [15x² - 17x - 4] (x + 2)

=[15x² -17x - 4]*(x) + [15x² - 17x -4]*2

= [15x²*x - 17x*x - 4*x ]+ 15x²*2 - 17x *2 - 4*2

= 15x³ - 17x² - 4x + 30x² - 34x - 8

= 15x³ <u>- 17x² + 30x²</u> <u>- 4x - 34x </u>- 8 {Combine like terms}

= 15x³ + 13x² - 38x - 8

Subtract. (5x2−3x−2)−(−2x2−x+10) Express the answer in standard form. Enter your answer in the box.

Nimfa-mama [501]

Answer:

$7x^{2}-2x-12=0$

Step-by-step explanation:

we know that

The standard form of the quadratic equation is equal to $ax^{2} +bx+c=0$

we have

$(5x^{2}-3x-2)-(-2x^{2}-x+10)$

eliminate the parenthesis

$5x^{2}-3x-2+2x^{2}+x-10$

group terms that contain the same variable

$(5x^{2}+2x^{2})+(-3x+x)+(-2-10)$

combine like terms

$7x^{2}-2x-12=0$
