Use the pythagorean theorem
a = 12
b = 5
c = unknown
a^2 + b^2 = c^2
12^2+5^2 = c^2
144 + 25 = c^2
169 = c^2
c^2 = 169
c = sqrt(169)
c = 13
The hypotenuse of the right triangle is 13 units
Answer: 13
Answer:
x = 15
Step-by-step explanation:
Bisects means divide in two equal parts.
Therefore, 74/2 = 37
37 = 2x+7
30 = 2x
15 = x
x = 15

Step-by-step explanation:
ax² + bx + c = 0
= ( - b ±
) ÷ 2a
~~~~~~~~~~~
g(x) = 3x - 7
g²(x) = (3x - 7)²
g²(x) = 9x² - 42x + 49
g²(
) = 9(
)² - 42(
) + 49
9(
)² - 42(
) + 49 = 8
16k² - 56k + 41 = 0
a = 16 , b = - 56 , c = 41
D = b² - 4ac = ( - 56)² - 4(16)(41) = 512 =
= ( 56 + √
) ÷ 32 =
+
=
