The area of a isosceles trapezoid height of 8 base of 10 base of 15

ikadub [295]

Answer:

A = 100 $un^{2}$

Step-by-step explanation:

You have to use the area of a trapezoid formula:

A = $\frac{h}{2}$ (a + b)

Now, substitute the values of the height and the bases:

A = $\frac{8}{2}$ (10 + 15)

Finally, simplify the equation to solve for the area:

A = 4(25)

A = 100 $un^{2}$

2x squared + x - 3 = 0

miskamm [114]

Step-by-step explanation:

_______________________________________

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

Write the equation

_______________________________________

$= 2 {x}^{2} + 3x - 2x - 3$

expand x into 3x and -2x

_______________________________________

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

take x out and 2x+3 in bracket and take - out and 2x+3 in brackets

_______________________________________

$= (2x + 3)(x - 1)$

Joe gave 1⁄4 of his total candies to his classmates. Then he gave 4/6 of what he had left to his brother when he went home. He t

lozanna [386]

Answer:

112 candies

Step-by-step explanation:

Start from the end.

Joe gave 25% of the remaining candies to his sister and has 21 candies left. Then

$21 \ candies - 75\%\\ \\x \ candies - 25\%$

Write a proportion:

$\dfrac{21}{x}=\dfrac{75}{25}\\ \\75x=21\cdot 25\\ \\x=\dfrac{21}{3}=7$

Joe gave 7 candies to his sister, so before this he had 21 + 7 = 28 candies.

He gave 4/6 of what he had left to his brother when he went home, so 2/6 of all his candies left ot him. Hence,

$28\ candies - \dfrac{2}{6}\\ \\x\ candies - \dfrac{4}{6}$

Write a proportion:

$\dfrac{28}{x}=\dfrac{\frac{2}{6}}{\frac{4}{6}}\\ \\\dfrac{28}{x}=\dfrac{1}{2}\\ \\x=28\cdot 2=56$

Joe gave 56 candies to his brother, so Joe had 28 + 56 = 84 candies when he went home.

Joe gave 1/4 of his total candies to his classmates, so 3/4 of his candies left to him. So,

$x\ candies - \dfrac{1}{4}\\ \\84\ candies - \dfrac{3}{4}$

Write a proportion:

$\dfrac{x}{84}=\dfrac{\frac{1}{4}}{\frac{3}{4}}\\ \\\dfrac{x}{84}=\dfrac{1}{3}\\ \\3x=84\\ \\x=28$

Therefore, initially, Joe had 28 + 84 = 112 candies.
