Answer:
-4
Step-by-step explanation:
The step of Talia that's incorrect is: C. step 3 because the slope ratio she calculated is incorrect.
<h3>What is the Slope?</h3>
The slope of a line (m) = rise/run = change in y / change in x.
Calculating the slope using two points on the line, (2, 5) and (1, 3), we should have:
Slope (m) = (5 - 3)/(2 - 1)
Slope (m) = (2)/(1)
Slope (m) = 2
This shows that the ratio of the slope calculated by Talia was wrong. The step that is incorrect is: C. Step 3

Answer:
B) 4 cm
Step-by-step explanation:
Pentagon ABCDE is 1.75 times larger than Pentagon LMNOP. In Pentagon ABCDE, side AB is 7 cm. The side across of it (DE) is also 7. Side DE is Side OP on Pentagon LMNOP. To solve for it, divide 7/1.75 to get 4.
Hope it helps!
Answer:
96 cm²
Step-by-step explanation:
The lateral surface area (A) is the sum of the areas of the 4 slant faces.
The faces are triangular with area
bh , thus
A = 4 ×
× 8 × 6 = 2 × 48 = 96 cm²
