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
Answer:
2/3
Step-by-step explanation:
2x + 5 = 8x+ 1
5 - 1 = 8x - 2x
4 = 6x
x= 4/6➡2/3
The opposite operation of squaring is to find the square root. I dunno what the original equation is so I can’t help with that
