The correct answer is 126
Answer:
Step-by-step explanation:
Length=18
Width/Breadth =10
Height=2
The formula for a diagonal face of a cuboid is=√(l²+ b²)
Face diagonal=√(18²+10²)
= 20.59 to 2.d.p
The formula for the body diagonal of a cuboid is=√(l² + b² + h²)
Body diagonal=√(18² + 10² + 2²)
=20.69 to 2.d.p
The answer is <span>y = x2 − 4
if you try to factor out all of the equations given to you (ex. 0=x2+4x+2), the only equation that can be factored out is </span><span>y = x2 − 4.
</span><span>
y = x2 − 4
</span><span>0= x2 − 4
</span>0=(x-2)(x+2)
0=x-2 0=x+2
2=x x=-2
