So in order to add the fractions together you need to first find a common denominator. For the very first problem you can use 63 as a denominator because 7*9=63. Now for the numerator. So you have 4/7 and 8/9. We just multiplied 7 by 9 so now we need to do that for 4 also. 4*9=36. Now we have 36/63. For 8/9 we multiply 8 by 7 to get 56. Now we have 36/63 + 56/63. Once you add those together you simplify your answer.
your answer would be y=-3x+14
Answer:
108° or Red
Step-by-step explanation:
This looks closest to a 108° angle.
108 - 7 = 101
101 ÷ 5 = 23
<em>x</em> = 23
Do the simple math for the rest of the angles...
Here is the math from where that leaves you...
127° (<em>b</em>) + 90° (<em>d</em>) + 136° (<em>e</em>) + 79° (<em>a</em>) + 108° (<em>c</em>) = 540°
P.S.
Rectangle answer must be 360° because 90° × 4 = 360°
Any additional vertices equals another 180° to the final number.
Answer:
10
Step-by-step explanation:
since it is a right angle triangle
![x = \sqrt[2]{(5 \sqrt{2} )^{2} +( 5 \sqrt{2})^{2}}](https://tex.z-dn.net/?f=%20x%20%3D%20%20%5Csqrt%5B2%5D%7B%285%20%5Csqrt%7B2%7D%20%29%5E%7B2%7D%20%20%2B%28%205%20%5Csqrt%7B2%7D%29%5E%7B2%7D%7D%20)
