Let length=x, witdth=x-9
Perimeter=130
2 length+2 width=130
2x+2(x-9)=130
2x+2x-18=130
4x=130+18
4x=148
X=37 cm
Length=37cm; width=37-9=28cm
Hope this can help.
Answer the top one is 0
Step-by-step explanation:
Let's solve your equation step-by-step.
x2−6x+10=0
For this equation: a=1, b=-6, c=10
1x2+−6x+10=0
Step 1: Use quadratic formula with a=1, b=-6, c=10.
± 
x = −(−6)± 
x= 6± 
x = 6± 
/ 2
x = 6 ± 
/ 2
6 ± 2i / 2 = 3 ± i
Answer:
A
Step-by-step explanation:
Since the slope is negative the line falls left to right.
Answer:
x ≥ 250
Step-by-step explanation:
Note that "greater than or equal to" looks like ≥
50 + x ≥ 300
Isolate the variable. What you do to one side, you do to the other. Subtract 50 from both sides.
x + 50 (-50) ≥ 300 (-50)
x ≥ 300 - 50
x ≥ 250
x ≥ 250 is your answer.
