Given equation is 2x²+x-28 = 0
⇛ 2x²+8x-7x-28 = 0
⇛ 2x(x+4)-7(x+4) = 0
⇛ (x+4)(2x-7) = 0
⇛ x+4 = 0 or 2x-7 = 0
⇛ x = -4 or 2x = 7
⇛x = -4 or x = 7/2.
Answer:
Value x = 8 make the equation true .
Step-by-step explanation:
Given : 3x = 24.
To find : Which value of x from the set {5, 6, 7, 8} makes this equation true?
Solution : We have given 3x = 24.
The equations are true when the Left hand side and right hand side of the equation are equal.
Then,
For x = 8 .
3 ( 8) = 24
24 = 24 .
Hence,
Left hand side = Right hand side.
Therefore, Value x = 8 make the equation true .
Answer:
5/14 ≈ 35.7%
Step-by-step explanation:
(12 +6) = 18 of the 28 students earned an A or a B. So, the experimental probability that a student did not earn that grade is ...
p(<B) = (28 -18)/28 = 10/28
p(<B) = 5/14 ≈ 35.7%

It's 11 because 6+5=11 other words it means it's 11 squares away
