Answer:
x=7
Step-by-step explanation:
Starting with (x-2)² = 25
First, square root both sides to get rid of the square on the left. You'll get:
x-2 = 5
Add 2 to both sides to get x alone. You'll get:
x=7
Check your answer by filling in 7 for x:
(7-2)² = 25
(5)² = 25
25 = 25
Answer:
43, 40
Step-by-step explanation:
1) Exterior angles are equal.
(x + 44) = 87 --> 87 - 44 = 43
x = 43
2) Alternate interior angles are equal.
(x - 30) = 70
x = 40
Given:
The height of ball is represented by the below function:
To find:
The number of seconds it will take to reach the ground.
Solution:
We have,
At ground level, the height of ball is 0, i.e., .
Taking out greatest common factor.
Splitting the middle term, we get
Using zero product property, we get
and
and
Time cannot be negative, so .
Therefore, the ball will reach the ground after 2 seconds.
Answer:
3x² + 2x + 18
Step-by-step explanation:
24x² + 16x + 144 .......simplify by 4
6x² + 4x + 36
3x² + 2x + 18
