Answer:

x=4.5 y=18.75

Step-by-step explanation:

solve using pythagorean theorem :

hypothenus²=opposite²+adjacent²

for y:

y²=15²+11.25²

y²=225+126.5625

y²=351.5625

y=18.75

for x:

7.5²=6²+x²

x²=7.5²-6²

x²= 56.25-36

x²=20.25

x=4.5

R=P over I squared. Solve for I.
kirza4 [7]

Answer: I=sqrt(P/R)

Step-by-step explanation:

R=p/I^2

Multiple l squared on both sides...

(I^2) R=p/l^2 (l^2)

R(I^2)=p

Separate I by dividing both sides by R...

I^2=p/R

Square root both sides...

I=sqrt(P/R)

The length of each side of a cube is x + 1 inches. What is the volume of the cube in cubic inches?
castortr0y [4]

Answer:

V = x³ + 3x² + 3x + 1 in³

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = s³ ( where s is the side ) , then

V = (x + 1)³

   = (x + 1)(x + 1)(x + 1) ← expand second pair using FOIL

   = (x + 1)(x² + 2x + 1) ← distribute

   = x³ + 2x² + x + x² + 2x + 1 ← collect like terms

   = x³ + 3x² + 3x + 1
