Find the value of x. x√5=x^4​
Kaylis [27]

Answer:

x=0,\sqrt[6]{5}

Decimal form,

x=0,1.30766048......

Step-by-step explanation:

x\sqrt{5}=x^{4}

x\sqrt{5}-x^{4}=0

(take x as a common factor)

x(\sqrt{5}-x^{3})=0

So,

x=0 and \sqrt{5}-x^{3}=0

for \sqrt{5-x^{3}=0

(add x^{3} for both sides)

\sqrt{5}=x^{3}

x=\sqrt[3]{\sqrt[2]{5} } (multiply 3 by 2)

x=\sqrt[6]{5}

So,

x=0,\sqrt[6]{5}

What is the value of x?<br>Enter your answer, as a decimal, in the box.​
Oksana_A [137]

Answer:

42.9m

Step-by-step explanation:

The topic is on similar triangle

you are comparing triangle MNP with triangle MAB

side AB is similar to NP

side MA is similar to MN

side MB is similar to MP

now MA = MN - AN

              = 67.2 - 32

               = 35.2m

MA/MN = MB/MP

35.2/67.2 = x/81.9

cross multiply and solve

x = 42.9m

A line passes through the point (-7,8) and has a slope of 1
Mila [183]

Answer:

y - 8 = x + 7

Step-by-step explanation:

To write the equation of a line use the point slope form. Substitute m = 1 and (-7,8).

y - y_1 = m(x-x_1)\\y - 8 = 1(x --7)\\y - 8 = 1(x + 7)\\y - 8 = x+7
