MARKING AS BRAINLIEST!! (Find area of each )

masha68 [24]

Answer:

38 km

Step-by-step explanation:

1. The formula to find the area of a trapezoid is $\frac{a+b}{2}h$ , where a and b are the bases and h is the height.

2. To find the area, all we have to do is plug in these values and simplify!

3. (Solving)

$\frac{a+b}{2}h$
$\frac{4.3+10.9}{2}*5$
$\frac{15.2}{2}*5$
$\frac{76}{2}$
$38$

Therefore, the area is 38 km.

PLEASE HELP!!!!

3241004551 [841]

Answer: Correct

Step-by-step explanation:

The conclusion is valid. Since $\overline{AB} \parallel \overline{DC}$ and $\overline{AD} \parallel \overline{BC}$ , we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since $\overline{AB} \cong \overline{BC}$ , we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.

Factorise x^2/4-y^2/4

Nuetrik [128]

Answer:

$\large\boxed{\left(\dfrac{x}{2}-\dfrac{y}{2}\right)\left(\dfrac{x}{2}+\dfrac{y}{2}\right)=\dfrac{x-y}{2}\cdot\dfrac{x+y}{2}}$

Step-by-step explanation:

$\dfrac{x^2}{4}-\dfrac{y^2}{4}=\dfrac{x^2}{2^2}-\dfrac{y^2}{2^2}\qquad\text{use}\ \left(\dfrac{a}{b}\right)^n=\dfrac{a^n}{b^n}\\\\=\left(\dfrac{x}{2}\right)^2-\left(\dfrac{y}{2}\right)^2\qquad\text{use}\ (a-b)(a+b)=a^2-b^2\\\\=\left(\dfrac{x}{2}-\dfrac{y}{2}\right)\left(\dfrac{x}{2}+\dfrac{y}{2}\right)=\dfrac{x-y}{2}\cdot\dfrac{x+y}{2}$

Please answer the following questions correctly.

Note that a translation along the horizontal is affected by the dependent variable. Hence the correct graphical representation will be Graph C

<h3>Translation and transformation</h3>

Translation is the transformation technique of changing the position of an object on the xy-plane.

Give the parent function f(x) = x^2, if the parent function is translated to the right by 4 units (along the horizontal), the resulting function h(x) will be (x+4)^2

Note that a translation along the horizontal is affected by the dependent variable. Hence the correct graphical representation will be Graph C
