The lest common multiple of 19 and 14 is 266
hope this helped
Change 4/5 - 2/3 so that the denominator is th same. Let’s try 15.
So, 12/15 - 10/15.
Then, subtract to get 2/15.
Hope it helped :)
Answer:
Total area = 29.8 sq. units
Step-by-step explanation:
<u>area of each triangle = sqrt(s * (s-a) * (s-b) * (s-c))</u>
to get the value of s, use the <u>semi-perimeter = s = perimeter / 2</u>
<u>Total area = area of triangle ABD + area of triangle ACD</u>
semi-perimeter of ABD = (3.48 + 8.66 + 8.6) / 2 = 10.37
semi-perimeter of ABD = (3.54 + 8.84 + 8.6) / 2 = 10.49
area of triangle ABD = sqrt(10.37 * (10.37-3.48) * (10.37-8.66) * (10.37-8.6))
area of triangle ABD = 14.7 sq. units
area of triangle ACD = sqrt(10.49 * (10.49-3.54) * (10.49-8.84) * (10.49-8.6))
area of triangle ACD = 15.08
Total area = 14.7 + 15.1
Total area = 29.8 sq. units
Answer:
18
Step-by-step explanation:
Adding the the two opposite integers will give zero
Answer:
second option
Step-by-step explanation:
x + y = 18 → (1)
4x - 3y = - 12 → (2)
Multiplying (1) by - 4 and adding to (2) will eliminate the x- term
- 4x - 4y = - 72 → (3)
add (2) and (3) term by term to eliminate x
0 - 7y = - 84
- 7y = - 84 ( divide both sides by - 7 )
y = 12
Substitute y = 12 into (1) and solve for x
x + 12 = 18 ( subtract 12 from both sides )
x = 6
solution is x = 6, y = 12
