I = 1
II = 1 + 1 = 2
V = 5
VI = 5 + 1 = 6
IV = 5 - 1 = 4
X = 10
A. XVIII = 10 + 5 + 1 + 1 + 1 = 18
B. VII = 5 + 1 + 1 = 7
C. XXVII = 10 + 10 + 5 + 1 + 1 = 27
D. XVII = 10 + 5 + 1 + 1 = 17
Answer: D. XVII
If to find the area of a triangle is to multiply 1/2 times the measure of the base times the height we need to make that equals to 18 since it’s already given. So 18=1/2 * ((h+1)*6)
Now we distribute
18 = 1/2 (6h + 6)
18 = 3h + 3 (Now we subtract 3 from both sides)
15 = 3h (now we divide both sides by 3)
5 = h
h = 5

Answer:
7 is A
Step-by-step explanation:
X+y=12 -- 1
3x+2y=29 -- 2
(1)x2
2x+2y=24 -- 1
(2)-(1)
x=5
Sub x into 1
x+y=12
5+y=12
y=7
Her two numbers are 5 and 7
