Making assumptions about where parentheses should be,
<span>Let u = -7x </span>
<span>du = -7dx </span>
<span>dv = e^(2x) dx </span>
<span>v = e^(2x)/2 </span>
<span>∫ -7xe^(2x) dx = </span>
<span>-7xe^(2x)/2 - ∫ e^(2x)/2 (-7) dx = </span>
<span>-7xe^(2x)/2 + 7e^(2x)/4 + c</span>
Area=basexhigh so, Area= 6x3 , so answer will be 18
The answer would be 108. 108:45 can be simplified to 12:5.
26.3 (5 out of 19) and 58.5 (72 out of 123)
May be wrong, but pretty sure it’s right
