Answer:
63.7 inches
Step-by-step explanation:
half the base is 9 inches, so the equal legs are each
L = √(9² +21²) = 22.8473...
Perimeter = 2(22.8473) + 18 = 63.6946... ≈ 63.7 inches.
Answer:
(5, )
Step-by-step explanation:
Given the 2 equations
5x + 7y = 40 → (1)
3x - 7y = 0 → (2)
Adding the 2 equations term by term will eliminate the y- term
8x + 0 = 40
8x = 40 ( divide both sides by 8 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (1)
5(5) + 7y = 40
25 + 7y = 40 ( subtract 25 from both sides )
7y = 15 ( divide both sides by 7 )
y =
solution is (5, )
n, n + 2 - two consecutive even integers
2n = (n + 2) - 16
2n = n + 2 - 16
2n = n - 14 |subtract n from both sides
n = -14
n + 2 = -14 + 2 = -12
Answer: -14, -12.
