Answer:
A=1665
Step-by-step explanation:
An area of a rectangle is length times width or l*w=a
The product is -10y² -19y +15.
1/5 of a foot
Simply subtract the height of Pancho’s sandcastle (3/5 of a foot) minus the height of his sister’s sandcastle (2/5 of a foot) to find a difference of 1/5 of a foot, meaning Pancho’s sandcastle was 1/5 of a foot taller than his sister’s sandcastle.
