Tara and Curtis are simplifying [4(10)-3^2]+6(4). is either of them correct? Explain your reasoning. Why wouldnt the -3^2 be pos
Maksim231197 [3]

Simplifying the given expression, it is found that Curtis is correct.

<h3>How to simplify the expression?</h3>

The expression to be simplified is given by:

[4(10) - 3²] + 6(4)

The non-related operations can be solved first, hence:

[4(10) - 3²] + 6(4) = [40 - 9] + 24

For the square, we have to consider that:

  • For -x², the negative is not part of the square, hence the result is negative, as - x*x = -x².
  • For (-x)², the negative is part of the square, hence the result is positive, as (-x)*(-x) = x².

The first bullet point is the reason that -3² = 9. Then, the simplified expression is completed as follows:

[40 - 9] + 24 = 31 + 24 = 55.

Which means that Curtis is correct.

The volume of a paper weight in the shape of a square pyramid is 48 cm3. Find the measure of one side of the base, if the height
Ulleksa [173]

The measure of one side of the base = 4 cm

Formula for the volume of a square pyramid V=\frac{1}{3}\times a^2h

The area of the base of the pyramid = 16 cm²

Length of the side of the base of the pyramid = 4 cm

Solution:

Given data:

Volume of a square pyramid = 48 cm³

Height of the square pyramid = 9 cm

Formula for the volume of a square pyramid:

$V=\frac{1}{3}\times a^2h, where a is one side of the base and h is height.

Substitute volume and height in the formula,

$48=\frac{1}{3}\times a^2\times9

$48=a^2\times 3

Divide by 3 on both sides of the equation,

$16=a^2 – – – – (1)

Taking square root on both sides of the equation, we get

a = 4

One side of the base = 4 cm

Area of the base = side × side

It is already found in equation (1),

Area of the base = 16 cm²

Length of the side of the base of the pyramid = 4 cm.
