Answer:
x = 5 ± √35
Step-by-step explanation:
Rewrite the left side as a square, then take the square root. Finally, add 5.
(x -5)² = 35
x -5 = ±√35
x = 5 ±√35
Answer:
1) b would be easier because it’s 1/2bh and since the base of 10 is easily divisible by 2 you don’t have to deal with fractions.
D=sqrt (x2-x1)^2+(y2-y1)^2
D=10
Step-by-step explanation:
Firstly add 7 to both sides= x/3= 5
Times by 3 on both sides to get x on its own= x= 15
