Helps plz,
-Dominant- [34]

Here's the solution,

there's a rectangle with sides 4x and 2x

So, area of rectangle :

=》4x × 2x

=》8x²

now, let's divide the kite into two equal triangles with base = 4x

and height = x

area of each triangle :

=》

\dfrac{1}{2}  \times base \times height

=》

\dfrac{1}{2}   \times 4x \times x

=》

2x \times x

=》

2{x}^{2}

now, area of each triangle = 2x²

and there are two triangles so,

Area of the kite will be :

=》2 × 2x²

=》4x²

Area of shaded region =

=》Area of rectangle - Area of kite

=》8x² - 4x² = 4x²

hence, correct option is B.

If anyone can, please help me. I have to determine the value of x.
zzz [600]

Answer:

60 I think

Step-by-step explanation:

draw a straight line to make it a triangle then you know that angles in a triangle add up to 180.

so,

180-140=40

180-100=80

40+80=120

180-120=60

x=60

I think it's 60

Please show me the steps of 78.32/0.22
iragen [17]
Let's solve this problem step-by-step.

STEP-BY-STEP EXPLANATION:

Let's first establish the problem as the following:

= 78.32 / 0.22

First, we will make the deniminator a whole number. In order to accomplish this, we will multiply both the numerator and denominator in the fraction by 100.

= ( 78.32 × 100 ) / ( 0.22 × 100 )

= 7832 / 22

Next we will divide both the numerator and denominator by the highest common factor ( HCF ) of the two numbers in order to simplify the fraction fully.

The highest common factor of 7832 and 22 is 22.

HCF = 22

This means that we will divide both the numerstor and denominator of the fraction by 22.

= ( 7832 ÷ 22 ) / ( 22 ÷ 22 )

= 356 / 1

= 356

FINAL ANSWER:

Therefore, the answer is: 356.

Hope this helps! :)
