Answer:

Step-by-step explanation:

(x + 3)^3/2 = 64

√(x + 3)^3 = 64

(x + 3)^3 = 64^2

(x + 3)^3 = (4^3)^2

(x + 3)^3 = (4^2)^3

Same exponent

x + 3 = 4^2

x + 3 = 16

x = 13

A(x, 1), B(5,3) and C(4,-3) are the vertices of triangle ABC. If AB=AC, find the value of x

Molodets [167]

$\\ \rm\longmapsto AB=AC$

$\\ \rm\longmapsto \sqrt{(x-5)^2+(1-5)^2}=\sqrt{(x-4)^2+(1+3)^2}$

$\\ \rm\longmapsto (x-5)^2+(-2)^2=(x-4)^2+4^2$

$\\ \rm\longmapsto (x-5)^2+4=(x-4)^2+16$

$\\ \rm\longmapsto (x-5)^2-(x-4)^2=16-4=12$

$\\ \rm\longmapsto x^2-10x+25-x^2+8x-16=12$

$\\ \rm\longmapsto -2x+9=12$

$\\ \rm\longmapsto -2x=12-9=3$

$\\ \rm\longmapsto x=\dfrac{3}{-2}=-1.5$

) What would the value of c be when

jasenka [17]

The value of c is 233.3

Step-by-step explanation:

Given equation is:

$\frac{18}{20}c-250=-40$

To find the value of c, we have to isolate c on one side of the equation

So,

Adding 250 on both sides

$\frac{18}{20}c-250+250=-40+250\\\frac{18}{20}c=210$

Multiplying by 20 on both sides

$20*\frac{18}{20}c=210*20\\18c=4200$

Dividing both sides by 18

$\frac{18c}{18}=\frac{4200}{18}\\c=233.3333$

Rounding off to the nearest one decimal place

c=233.3

The value of c is 233.3

Which of the following could be the lengths of the sides of a 30°-60°-90° triangle?

Inga [223]

According to Pythagoras theorem

a^2+b^2=c^2

similarly ,

3^2+ 4^2= 5^2

9+16=25
25=25

LHS=RHS
so angle of triangle is 30 , 60 and 90

answer is 3,4,5
