Answer:
d. 10
Step-by-step explanation:
If the formula is V= Ab x H
then the base and height is 4 and 7.5 because it doesn’t need to be the bottom so you multiply 7.5 x 4= 30 but we have to half it since it’s a triangle which is 15 and then multiply 10 which gives us 150 cm squared.

Step-by-step explanation:
3.4+0.5y +1.1=-4.5
3.4+1.1+0.5y= -4.5
4.5+0.5y=-4.5
move 4.5 to the other side
sign changes from +4.5 to -4.5
4.5-4.5+0.5y= -4.5-4.5
0.5y= -4.5-4.5
0.5y=-9
divide both sides by 0.5
0.5y/0.5= -9/0.5
Answer: y= -18
