The answer is 76. multiply 15 times 4 which is 60.
and the triangle is the difference of the sides, so 19-15=4.
so then multiply the base and height, this leaves 4x4 which is 16.
then add the two. 60+ 16= 76
The answer, im assuming is D. for Tuesday
3(x-2)+4(2x-3)
Use distributive property
3(x)-3(2)+4(2x)-4(3)
=3x-6+8x-12
Combining like term
3x+8x-6-12
=11x-18. As a result, 11x-18 is another expression that equivalent for 3(x-2)+4(2x-3). Hope it help!
Im guessing it'll be C, but im not sure so im sorry if this didnt help
