4) fifteen less than y is 32
15 - y= 32
15 - (-17)= 32
two negatives become positive so 15+17= 32
To find the area you have to have a formula,
A= S²
A=3 2/5× 3 2/5
A=289/25
A=11 14/25
The Answer:
-69510 divide 22=
3,159.545454545455
The answer is -1.1
To get that i just subtracted 2.4 by 1.3 and then just carried over the negative sign
BC is 3 across & CA is 3 up, but this creates a right-angle triangle. So, Pythagoras Theorem is used to find AB
AB = root 3^2 + 3^2
AB = 3 root 2
or 4.242640687
Thus, AB is 4.24 to 2d.p
(root means square root)
Hope this helps!
