Answer:

42 $cm^{2}$

Explanation:

When finding the area of a triangle, the first step is to multiply the length times the width, in this case- 7 $cm$ and 12 $cm$ . 7 × 12 equals 84. The next step in finding the area would be to cut the product in half, in this case- the product is 84, so you would do 84 ÷ 2. And 84 ÷ 2 is 42, hence the answer would be 42 $cm^{2}$ .

Hope this helps, and have a fabulous day!

Five devied by three forths

bija089 [108]

Answer:

$6\dfrac{2}{3}$

Step-by-step explanation:

$\dfrac{5}{\dfrac{3}{4}} = \dfrac{5}{1}\times\dfrac{4}{3}=\dfrac{20}{3}=6\dfrac{2}{3}$

When dividing fractions, you just need to remember that all you need to do is get the inverse of the divisor and multipy.

So for the problem

5 = divident

3/4 = divisor

So we get the inverse of 3/4 which is 4/3 and then multiply.

Look above to see the process.

(Squreroot x+2)(squreoot x-2)=0

yuradex [85]

Answer:

$\boxed{ \ x = 2 \ or \ x = -2 \ }$

Step-by-step explanation:

I understand that you want to solve this equation

$\sqrt{x+2}\sqrt{x-2}=0$

<=>

$\sqrt{(x+2)(x-2)}=0$

<=>

$(x+2)(x-2)=0$

<=>

x = 2 or x = -2

hope this helps

if your question is $(\sqrt{x}+2)(\sqrt{x}-2) = 0$

then this is $(\sqrt{x})^2-4 = 0\\ x = 4$
