Answer:
4) c = 10
5) b = 10
6) b = 12
7) a = 4
Step-by-step explanation:
<h3>Pythagorean Theorem = a^2 + b^2 = c^2</h3>
to solve these, just substitute a, b, and c for the values given.
4) a = 8, b = 6
a^2 + b^2 = c^2
8^2 + 6^2 = c^2
64 + 36 = c^2
100 = c^2
c =
c = 10
5) a = 24, c = 26
a^2 + b^2 = c^2
24^2 + b^2 = 26^2
576 + b^2 = 676
subtract 576 from both sides
b^2 = 676 - 576
b^2 = 100
b = 10
6) a = 5, c = 13
a^2 + b^2 = c^2
5^2 + b^2 = 13^2
25 + b^2 = 169
subtract 25 from both sides
b^2 = 169 - 25
b^2 = 144
b = 12
7) b = 11, c =
a^2 + b^2 = c^2
a^2 + 11^2 = 137
a^2 + 121 = 137
a^2 = 137 - 121
a^2 = 16
a = 4
Answer:
f(x+2) = - 6x - 5
Step-by-step explanation:
As we have f(x) =- 6x + 7, then we also have f(x+2) = - 6(x+2) + 7 = - 6x - 12 + 7 = - 6x - 5.
<span>3[-x+(2x+1)]=x-1
</span><span>3[x+1]=x-1
3x + 3 = x -1
3x - x = -1 -3
2x = -4
x = -4/2
x = -2</span>
The answer is A.
first, calculate the totals for each company. what you do is take the number and divide it by 6.
154.2 ÷ 6 = 25.7
165.6 ÷ 6 = 27.6
Then, add both together.
25.7 × 27.6 = 54.3.
You can conclude that X is smaller than Y. For example:
(2,5)
2 + 5 = 7
2 - 5 = -3
Hope this helped!
