Answer:
40
Step-by-step explanation:
P=2(l+w)
2·(10+10)
=40
Answer:
of solving for a A=5w
if solving for w W=A over 5
y=x²-10x-7
a>0 so we will be looking for minimum
x=-b/2a=10/2=5
y=25-50-7=-32
Answer: (5;32)
y=-4x²-8x+1
а<0 so we will be looking for maximum
х=-b/2a=8/-8=-1
у=4+8+1=13
Maximum point (-1;13)
Factors are numbers we can multiply together to get another number:
<span>Example: 2 and 3 are factors of 6, because 2 × 3 = 6.
