simon says that to find the area of a trapezoid, you can multiply the height by the top base and the height by the bottom base.
Then add the two products together and divide the sun by 2. Is Simon correct? Explain your answer.
2 answers:
He is correct
basically you have
h times base1+h times bsae 2 all divided by 2
that equals
(hb1+hb2)/2
if we undistribute h using distributive property which is ab+ac=a(b+c)
(h)(b1+b2)/2
if you split the trapezoid in half with a horizontal line that passes through the halfway point of the height and take those two shapes and put them side by side and cut the triangles off the ends and add them, you will see why this is true
the reason is becuase you can get to the area formula from that is height times (b1+b2)/2

Answer:
<em>La masa del paracaidista es 7.14 Kg</em>
Step-by-step explanation:
<u>Peso y Masa</u>
La masa de un objeto es una medida de la cantidad de material que el objeto posee. Sus unidades más comunes son el Kg, gr, lb, Ton.
El peso de un objeto de masa m es la fuerza con la cual la Tierra atrae al objeto a través de la aceleración de gravedad g. Sus unidades son iguales a las de cualquier fuerza, es decir, Nw, Kgf, Dina. Su fórmula es:
P=m.g
Si tenemos el peso P=70 N, podemos calcular la masa, despejándola de la fórmula:
Sustituyendo los valores:
La masa del paracaidista es 7.14 Kg
Step-by-step explanation:
For equation N°2
Solving algebraically:
(Sum x on both sides of the equation)
Resolving graphically:
x = -2 --------- - (- 2) -3 = -1 pto (-2, -1)
x = -4 ---------- - (- 4) -3 = 1 pt (-4.1)
x = -3 --------- - (- 3) -3 = 0 pt (-3.0) Solution
The graphic is shown in the attached image. The red dot in the graph represents the solution
For equation N° 4
Solving algebraically:
(Sum -3 on both sides of the equation)
(divided by 9 on both sides of the equation)
(simplifies the fraction)
Resolving graphically:
x = 1 --------- 9 (1) +3 = 12 pt (1.12)
x = -1 --------- 9 (-1) +3 = -6 pto (-1, -6)
x = -1 / 3 -------- 9 (-1/3) +3 = 1 pt (-1 / 3.0) Solution
The graphic is shown in the attached image. The red dot in the graph represents the solution
For equation N°. 6.
Solving algebraically:
(Sum -4x on both sides of the equation)
The equation is not met, the x are eliminated, therefore, it has solution
For equation N°. 8
Solving algebraically:
(Sum 6x on both sides of the equation)
The x are eliminated, 3 is not equal to 5, the equality is not met. The equation has no solution.
