Answer:
x = 12
Step-by-step explanation:
5x - 7 = 3x + 17
2x -7 = 17
2x = 24
x = 12
Answer:
-4/9 is a rational number
Step-by-step explanation:
Rational numbers are the numbers you can make by dividing one integer by another, so in other words a fraction.
Surface area of a cuboid
= [2(length)(width)] + [2(width)(height)] + [2(height)(length)]
= {[2(4)(2.5)] + [2(2.5)(2)] + [2(2)(4)]} units²
= (20 + 10 + 16) units²
= 46 units²
Answer:
<h2>4(5x + 6)</h2>
Step-by-step explanation:
Answer:
5 Outer and 1 lone pair
Step-by-step explanation:
A square pyramidal shape results when one of the bonds of an octahedron structure is occupied by a lone pair.
Hence there are 5 bonded atoms and one lone pair. The hybridization about the central atom is 
.
One of the most common example is Xenon tetraflouride. 
. Looking at its structure we can see that it has 5 pairs of outer atoms and one lone pair. With its coordination number 5. The shape of the orbitals is octahedral.
