A

The volume (V) of a pyramid is found using the formula

V = \frac{1}{3} × area of base × height(h)

area of base = 9² = 81 ← area of a square, hence

324 = \frac{1}{3} × 81 × h = 27h ( divide both sides by 27 )

h = \frac{324}{27} = 12 → A

Rasek [7]

Answer:

Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7

Step-by-step explanation:

-1.7 + (-6.3)

Correct simplification

-1.7 + (-6.3)

Open parenthesis

= - 1.7 - 6.3

= -8

NOTE:

- * + = -

- * - = +

+ * - = -

+ * + = +

Maureen's simplification

-1.7 + (-6.3)

= 1.7 - 6.3

= -4.6

Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7
