4)
Area=(base x height) / 2
area=24 in²
therefore:
(b*3b)/2=24 in²
3b²/2=24 in²
b²=(24*2)/3 in²
b²=16 in²
b=√(16 in²)= 4 in
answer: 4 in
5)
if x=9
x²+z=103
(9)²+z=103
81+z=103
z=103-81=22
if x=-9
(-9)²+z=103
81+z=103
z=103-81=22
Answer: 23
1)
n²-49=0
n²=49
n=⁺₋√49=⁺₋7
Answer: ⁺₋7
2)
x²+64=0
x²=-64
x²=⁺₋√-64 These numbers are not real.
Answer:no solution
3)
area=slide²
slide=+√area
slide=+√(144x²)=12x
answer: 12 x
The first option is the correct quadratic formula
A: Speed is Independent as it can be anything with no restrictions. Gas mileage is dependent as it relies on the value of speed for its value to be decided.
B: The first letter of speed is "S" so it can represent the variable. The first letter of mileage is "M" so the variable can be represented by that letter. It really can be any letter.
C: no context
D: no context
Answer:x=1/2
Step-by-step explanation:5x-5-6x=-11x
-x-5=-11x
-x+11x=5
10x/10=5/10
X=1/2
