This would be a lot easier with the figure.
Four equal spaces means quarters.
A is 1 mark to the left of 0, so 1/4 to the left of 0. That's -1/4
Answer: Negative one-fourth
No the side’s are different
Answer:
x=1/3 or x=−3/2
Step-by-step explanation:
7x2+10x−3=x2+3x
Step 1: Subtract x^2+3x from both sides.
7x2+10x−3−(x2+3x)=x2+3x−(x2+3x)
6x2+7x−3=0
Step 2: (3x−1)(2x+3)=0
Step 3: Set factors equal to 0.
3x−1=0 or 2x+3=0
x=1/3 or x= −3/2
3z - 12 = 63
+ 12 +12
3z = 75
z = 25
x + 63 = 180
- 63 - 63
x = 117°
Step-by-step explanation:
90-2x + 3x + 60 = 180
90 + x + 60 = 180
x + 150 = 180
x = 30°
