Step-by-step explanation:
Okay, so there are 6 faces on this prism. 2 of them are 6inx10in, two are 4inx6in, and two are 10inx4in.
2(6 x 10) + 2(4 x 6) + 2(10 x 4)
= 2(60) + 2(24) + 2(40)
= 120 + 48 + 80
= 248 square inches (or in^2)
Answer:
y = -13.5
x = -10.5
Step-by-step explanation:
Hi there!
Let the two numbers be equal to <em>x</em> and <em>y</em>.
The difference of two numbers is 3 ⇒ x - y = 3
Their sum is - 24 ⇒ x + y = -24
Solve using elimination:
x - y = 3
x + y = -24
Add the two equations:
x + x - y + y = 3 - 24
2x = -21
x = -10.5
Solve for y:
-10.5 - y = 3
- y = 3 + 10.5
y = -13.5
I hope this helps!
