a = 15/28

Step-by-step explanation:

As long as the bases are the same, in this case 2, keep the base and add the exponents when multiplying

keep the base and subtract the exponents when dividing

1/4 + 3/7 = 3/28 + 12/28 = 15/28

Please help me I’m stuck

Gre4nikov [31]

Answer:

$x = 3.7$

Step-by-step explanation:

We can find the side of the hypotenuse by applying pythagorean theorem.

${5}^{2} + {5}^{2} = {x}^{2}$

$25 + 25 = {x}^{2}$

$50 = {x}^{2}$

$x = 5 \sqrt{2}$

Now we can apply pythagorean theorem on the other triangle

$(5 \sqrt{2} ) {}^{2} + {x}^{2} = {8}^{2}$

$50 + {x}^{2} = 64$

${x}^{2} = 14$

$x = \sqrt{14}$

$x = 3.7$
