$~~~\text{Area of triangle} = \dfrac 12 \times \text{Base} \times \text{Height}\\\\\implies 10 = \dfrac 12 \times 5 \times w\\\\\implies w =\dfrac{20}5 \\\\\implies w = 4 ~cm$

Answer:

4cm

Step-by-step explanation:

» Concepts

The area of a triangle is how much space is in the triangle. The formula for the area of a triangle is $\frac{1}{2} bh$ , where b = base and h = height.

» Application

We're given the area as 10 cm² and the base as 5 cm. Thus, we have to plug these values into the formula to solve for the height.

» Solution

$10=\frac{1}{2} *5*h$
$10=\frac{5}{2}h$
$10*2/5=5/2(h)*2/5$
$h=4$

Answer:

<h3> None of given </h3><h3> x = -1²/₇ </h3>

Step-by-step explanation:

-(-10x - 8) = -(4x + 10)

10x + 8 = -4x - 10

-8 -8

10x = -4x - 18

+4x +4x

14x = -18

÷14 ÷14

x = -¹⁸/₁₄ = -⁹/₇ = -1²/₇

I think you meant -(10x-8)=-(4x+10)

Then:

-(10x - 8) = -(4x + 10)

-10x + 8 = -4x - 10

-8 -8

-10x = -4x - 18

+4x +4x

-6x = -18

<h2>Solution -: </h2>

Example -1 

Here we have ,,, 

$(6 \: x) { \frac{9}{5} }^{}$

solve -; 

6x ^9×1/5

 $\big[(6x \: ) {}^{9} ] {}^{ \frac{1}{5} }$ 

Convert on radical form 

 $\sqrt[5]{(6x) {}^{9} }$ 

Example -2 

 $\displaystyle{}a {}^{ \frac{2}{5} } \\ = \sqrt[5]{x {}^{2} } \: \: \: \: \: \: \: \because ( \sqrt[m]{x {}^{n} } )$
