1. Three less than the square of a number can be
1 answer:
Answer:
D)
Step-by-step explanation:
As if a statement is given which says that :Three less than the square of a number.
This means if the number is 'x'
Suppose the statement is : the value of y is 3 less than the square of x then the equation will be
By using two such statement that gives two equation we can find the value of x and y by solving one equation and putting it in the other equation which will give the values of two variables .

Answer: The answer is D. Trapezoid.
Step-by-step explanation: As shown in the attached figure, a rectangular pyramid ABCDE is drawn. We are slicing this rectangular pyramid parallel to the base BCDE at the points F, G, H and I.
We can clearly see from the figure that upper half of the sliced figure will be similar to the pyramid BCDE and the lower sliced figure will be a trapezoid. These are the three-dimensional figures.
Also, the sliced two-dimensional figure FGHI will be a rectangle, because
the pyramid is a rectangular one and so, FI=GH, FG=HI and all the angles are right angles.
Thus, the resulting two-dimensional figure will be a rectagle.
