Answer:what are the options
Step-by-step explanation:
To solve 47, you would add.
a² (33) + b²(44) = c²
33² = 1,089
44²= 1,936.
1,089 + 1,926= 3,024.
√3,024= 54.9
to solve 48, you would subtract.
9² - 5.4² =x²
9² = 81.
5.4²= 291,16.
81 - 29.16= 51.84.
√51.84=7.2
7.2 = x
hopefully this helps
-4K = 1.2 + 6
-4K = 7.2
-4K/-4 = 7.2/-4
Therefore k = -1.8
Answer: x = -2
<u>Step-by-step explanation:</u>
Find 2 numbers whose product is the c-value of 4 and their sum is the b-value of 4.
x² + 4x + 4 = 0
∧
1 + 4 = 5
2 + 2 = 4 <em>this works!</em> <em>so the factors are: </em>
(x + 2)(x + 2) = 0
x + 2 = 0 and x + 2 = 0
x = -2 and x = -2 --> <em>same answer so only need to list it once</em>
Answer:
36
Step-by-step explanation:
10% of 360=10/100*360=1/10*360=360/10=36
