Complete the square to transform the expression x^2+4x 2 into the form a(x − h)2 + k.
faust18 [17]

Answer:

(x+2)^2-2

Step-by-step explanation:

we have the expression

x^2+4x+2

Convert to vertex form

a(x-h)^2+k

where

a is the leading coefficient

(h,k) is the vertex

Complete the square

(x^2+4x+2^2)+2-2^2

(x^2+4x+2^2)-2

Rewrite as perfect squares

(x+2)^2-2

so

The coefficient a =1

The vertex is the point (-2,-2)

Volume question
ioda

Answer:

The answer is 61.4 L

Step-by-step explanation:

Using the formula of cuboid, V = l×b×h, to find the total amount of water contained :

l = 120cm

b = 40cm

h = 15cm

V = 15×120×40

= 72 000cm³

= 72 L

It is given that she uses 10.6L for shower. Then calculate the remaining water by substracting 10.6L from the original amount of water :

remaining = 72 - 10.6

= 61.4 L
