Answer:

A square

Step-by-step explanation:

A parallel cross section will be the same shape of the base. Since it's a square base, all parallel cross sections will also be parallel. Think of it as a different floor of a pyramid shaped building.

Answer:

Cross section taken parallel to the base will be SQUARE.

Step-by-step explanation:

When we take a cross section of a pyramid parallel to the square base, means that we are creating a new base for the same structure.

Cross section parallel to the base of a square base will look like a square in shape with smaller dimensions.

So the answer is SQUARE shape.

Solve the equation: 5x + 7= 7x +23

olga nikolaevna [1]

Answer:

x = -8

Step-by-step explanation:

1) 5x + 7= 7x +23

Move the terms

2) 5x + 7 -7x = 23

Collect like terms

3) 5x -7x = 23 - 7

Calculate

4) -2x = 16

Divide both sides by <em>-2</em>

5) x = -8

17) $x-8=11$

18) $9-x=5$

19) $x+6=7$

20) $x+(-4)=-18$

Step-by-step explanation:

17) The difference between a number and 8 is 11

Let number = x

then the equation will be:

$x-8=11$

Solving:

$x-8=11$

$x=11+8\\x=19$

18) Nine less than a number is five.

Let number = x

then the equation will be:

$9-x=5$

Solving:

$9-x=5\\-x=5-9\\-x=-4\\x=4$

19) Seven is equal to a number plus 6

Let number = x

then the equation will be:

$x+6=7$

Solving:

$x+6=7\\x=7-6\\x=1$

20) The sum of a number and -4 is -18

Let number = x

then the equation will be:

$x+(-4)=-18$

solving:

$x+(-4)=-18\\x-4=-18\\x=-18+4\\x=-14$

This is something you should memorize. Specifically it is from the Empirical Rule (or 68-95-99.7 rule) which gives rough approximations of areas under the curve.
