Answer:
Step-by-step explanation:
4(9) + 2(9)
36 + 18
54
4m + 2m, when m=9
<u>Substitute m with 9</u>
4(9)+2(9)
4 × 9 + 2 × 9
<u>Multply, 4×9= 36</u>
36 + 2 × 9
<u>Multply, 2 × 9= 18</u>
<u>Add 36+18</u>
Hope this helps u!
well 9+10=21
like regular
x = 1.3
15 - 4x = 2(3x + 1)
15 - 4x = 6x + 2
-2 -2
--------------------------
13 - 4x = 6x
+4x +4x
13 = 10x
/10 /10
---------------------------
1.3 = x
about 50
that's all I can think of
Look at the picture.
Use the Pythagorean theorem:
substitute
