Answer:
7
Step-by-step explanation:
let the no. be 'x'
By question,
2x-8=6
or, 2x =6+8
or,2x = 14
or,x = 7
therefore, the no. is 7.
Answer:
A
Step-by-step explanation:
imagine the shape is flipped and standing up. that's how you can compare both images.
Answer:
C) (1,0), and (-3,0)
Step-by-step explanation:
The parabola intercepts the x axis at points (1,0) and (-3,0).
11.7
Formula: a^2 + b^2 = c^2
so substitute the numbers like this:
10^2 + 6^2 = c^2
both 10^2 and 6^2 are perfect squares:
10 × 10= 100 and 6 × 6= 36
100 + 36= c^2
add:
100 + 36 =
136 = c^2
now in order to get rid of the squared, you put it into a radical:
√136 = √c^2
note: whatever you do on one side, you do to the other
it's easier to use the calculator for this so put √136 and you're gonna get 11.66
since it's asking you to round it to the nearest tenth:
11.66 = 11.7
sorry if the explanation is kinda long ✋ i tried explaining it better in the end but i failed
