Answer: last option. 9.2
Step-by-step explanation:
The pythagoreon theorm tells us, a^2+b^2 = c^2. We can substitute these values, so 7^2 + 6^2 = x^2 => 49+36 = x^2 => root of 85. The root of 85 is 9.219 something so you can round 9.219 to 9.2.
Answer:
8
Step-by-step explanation:
<h2>—Math</h2>

x = √64
x = 8
Answer:
Step-by-step explanation:
(1): "a2" was replaced by "a^2"
((2a2 + 8ab) - 3a) - 12b
2a2 + 8ab - 3a - 12b
Answer:
1)49
2)231
Step-by-step explanation:
1)
4+9=13
4*2=8
8+1=9
2)
2+3+1=6
2+1=3
1*2=2
(y + z2) * x
(5 + 3(2)) * 2
(5 + 6) * 2
11 * 2
Your answer is 22
