A craftsman is making a dulcimer with the same dimensions as the one shown. The surface shown requires a special, more durable t

Bogdan [553]

Answer:

$\displaystyle A=\frac{3h^2}{2}+h$

Step-by-step explanation:

Area of trapezoid

Given a trapezoid shape whose parallel sides measure b1 and b2 and whose height (perpendicular to the base) is h, then the area of the trapezoid is given by

$\displaystyle A=\frac{b_1+b_2}{2}\cdot h$

The dulcimer has the following dimensions

$b_1=2h+1$

$b_2=h+1$

and height h

Thus

$\displaystyle A=\frac{2h+1+h+1}{2}\cdot h=\frac{3h+2}{2}\cdot h$

Operating

$\displaystyle A=\frac{3h^2+2h}{2}=\frac{3h^2}{2}+h$

$\boxed{A=\frac{3h^2}{2}+h}$

Is the required polynomial

(4m-3n)^2 Multiplying Polynomials

Sindrei [870]

Answer:

4m²-24mn+9n²

Step-by-step explanation:

Separate equation out so it is (4m-3n)×(4m-3n)
FOIL (First, Outside, Inside, Last) your polynomial
Should have equation 4m²-12mn-12mn+9m²
Combine like terms
Result: 4m²-24mn+9m²

Solve for x: −2(4 − 2x) + 3x = 2x + 2(5 + x) − 6

worty [1.4K]

Answer:

x=4

Step-by-step explanation:

−2(4 − 2x) + 3x = 2x + 2(5 + x) − 6 (DISTRUBUTE)

-8+4x+3x=2x+10+2x-6 (SIMPLFY)

-8+7x=4x+4 (SUBTRACTE 4X FROM BOTH SIDES)

3x-8=4 (ADDD 8 TO BOTH SIDES)

3x=12 (DIVIDE MY 3 ON BOTH SIDES)

x=4
