Answer:
r + s = -4
Step-by-step explanation:
3r + 2s = r - 8
3r + 2s - r = -8
2r + 2s = -8
r + s = -8/2
r + s = -4
Answer:
24cm
Step-by-step explanation:
The area of the rectangle is length × breadth. You already know the area and the breadth, so you can find the length.
288cm² = length × 12cm
length = 288cm² ÷ 12cm
= 24cm
A. given
b. distributive property (a(b+c)=ab+ac)
c. addition or commutative property (a+b=b+a)
d. subtraction property of equality (if a=b, then a-c=b-c)
e. division property of equality (if a=b, then a/c=b/c)
f. equality property (if a=b, then b=a)
Answer:
24x+48
Step-by-step explanation:
(3x+6)(8)
=8(3x+6)
=(8*3x)+(8*6)
=24x+48
Answer:
D) n(c) = c/15 - 2.
Step-by-step explanation:
c(n) = 15n + 30
c = 15n + 30
15n + 30 = c
15n = c - 30
n = c/15 - 2
D) n(c) = c/15 - 2
Hope this helps!
