If you run a plane like in the picture below, I don't think you could get an isosceles triangle, namely, a triangle with two equal sides.

If a^2+b^2= 4 and ab = 5, what is the value of (a+b)^2? A. 10 B. 12 C. 14 D. 16

wlad13 [49]

Answer:

Step-by-step explanation:

(a+b)^2

(a+b)(a+b)

FOIL

a^2 + ab+ab + b^2

Combine like terms

a^2 +2ab + b^2

Rearranging

a^2+b^2 +2ab

We know a^2+b^2 = 4 and ab= 5

4 + 2(5)

4+10

The volume of a gas "V" varies inversely with the pressure "P" put on it. If the volume is 360cm³ under a pressure of 20 kgcm2

Sav [38]

Answer:

15 Kg cm²

Step-by-step explanation:

Given that V varies inversely with P then the equation relating them is

V = $\frac{k}{P}$ ← k is the constant of variation

To find k use the condition

V = 360, P = 20, then

360 = $\frac{k}{20}$ ( multiply both sides by 20 )

k = 7200

V = $\frac{7200}{P}$ ← equation of variation

When V = 480, then

480 = $\frac{7200}{P}$ ( multiply both sides by P )

480P = 7200 ( divide both sides by 480 )

P = 15
