-14.9 = -15

-2.3 = -2

So estimate:

3 + (-14.9)(-2.3)

= 3 + (-15) (-2)

= 3 + 30

=33

A diagonal of a cube measures
Gennadij [26K]

Answer: 7cm

Step-by-step explanation:

Use pythagorean theorum:

Variables:

Let the edge = A

Face diagonal (F) = 10cm

Inner diagonal (I) = sqrt(150) cm

A^2 = I^2 - F^2

A^2 = [sqrt(150)]^2 - 10^2

A^2 = 150 - 100

A^2 = 50

A = sqrt(50)

A = 7.0710678 cm

A = 7cm (to the nearest tenth)

so, length of an edge = 7cm

Sort each equation according to wether it has one solution, infinitely many solutions, or no solution
katovenus [111]

Answer:

5(x - 2)=5x-7 has no solution

-3(x - 4)=-3x+12 infinitely many solutions

4(x+1)=3x+4 no solution

-2(x - 3)=2x-6 infinitely many solution

6(x + 5)=6x+11 no solution

Step-by-step explanation:

5(x - 2)=5x-7

-3=0

-3(x - 4)=-3x+12

0=0

4(x+1)=3x+4

x=0

-2(x - 3)=2x-6

0=0

6(x + 5)=6x+11

30=11

I hope this helps.
