Answer:
B
Step-by-step explanation:
The answer is D) 15 square units for the formula of a parallelogram is length times height, the way I solved it was I graphed to get a visual and understand , I see that the height is 3 and the length is 5 so 3•5 is 15

A. The Area of one triangular face would be 320 ft². B. The total surface area, in square feet, of the square pyramid is 2,304 ft².
<h3>What is the area of the triangle?</h3>
The Area of one triangular face can be calculated as;
A = area of triangle = ½ x b x h
Where,
b = 32 ft
h = 20 ft
A = ½ x 32 x 20 = 16 x 20
A = 320 ft²
Area of 1 triangular face = 320 ft²
B.
Total surface area = area of the 4 triangular faces + area of the base of the square pyramid
T.S.A = 4(320) + (s²)
Where,
s = 32 ft
T.S.A = 4(320) + (32²)
T.S.A = 1,280 + 1,024
= 2,304 ft²

Answer:
3x+5≥7
3x≥7-5
3x≥2
x≥⅔
interval notation: [⅔; +infinity[
Let me know is your inequation is 3x+5>-7.
if it's not this ≥ then let me correct.
thanks
