Answer: um im not really sure what you want here but im pretty sure thats the answer right there, dont know what else to say.
Answer:
L=7 units and B=3 units
Step-by-step explanation:
L=B+4 ... Equation 1
P = 20
P=2(B+L)... Equation 2
20=2(B+B+4)... Substituting equation 1 to equation 2
20=2(2B+4)
20=4B+8
20-8=4B
12=4B
12/4=4B/4
B=3... Solve for B
L=B+4
L=3+4
L=7... Solve for L
1. One value of x for f(x)=-4 would be 0.
2. Should be 3.5 and -3.5 but I'm not sure
"Sum" is addition.
3(15)+4(2)
First simplify by multiplying 3 by 15 and 4 by 2.
45+8
Now simply add. :)
45+8=53
The answer is 53. :)
-17+32+-9+0+52+12+-14= 56
56 ÷ 7 = 8
mean is 8
