Answer:
2
Step-by-step explanation:
Given in the question,
a + b = √17
(a+b)² = 17
a² + b² +2ab = 17
a² + b² = 17 - 2ab
<h3>Area of triangle </h3>
1/2 (h)(b)
here h is perpendicular height of triangle = a
b is the base of triangle = b
<h3>Use pythagorus theorem:</h3>
hypotenuse² = base² + height²
3² = a² + b²
9 = a² + b²
9 = 17 - 2ab
9 - 17 = -2ab
-8 = -2ab
cancel minus on both sides
8 = 2ab
ab = 8/2
ab = 4
Plug ab in the formula of area
1/2 (h)(b)
1/2 (a)(b)
1/2 (4)
4/2

Answer:
20?
Step-by-step explanation:
Answer: 59 feet
Step-by-step explanation:
First the sea turtle descended 28 feet.
It then ascends 5 feet which means it is now:
= 28 - 5
= 23 feet below surface
It then descends 9 feet and repeats that descent 4 time:
= 9 * 4
= 36 feet below the surface
Total distance below the surface:
= 23 + 36
= 59 feet
7c + 12 = -4c + 78
+4c. +4c
11c + 12 = 78
-12. -12
11c = 66
11/11. 66/11
C = 6
Plug in the answer to check .
7 * 6 + 12 = 54
-4 * 6 + 78 = 54
54 = 54
