Factor -1 out of -3.6z -10.8
your answer should be -(3.6z+10.8)
Answer:
The length of the hypotenuse ≈ 39.7 cm
Explanation:
Since the given triangle is a right-angled triangle, this means that we can apply the Pythagorean theorem.
The equation for Pythagorean calculation is:
(hypotenuse)² = (first leg)² + (second leg)²
In the given, we have:
first leg = 30 cm
second leg = 26 cm
Substitute with the givens in the above equation to get the hypotenuse as follows:
(hypotenuse)² = (30)² + (26)²
(hypotenuse)² = 1576
This means that:
either hypotenuse = √1576 = 39.69 ≈ 39.7 cm ..........> accepted
or hypotenuse = -√1576 = -39.69 ......> rejected as length can't be negative
Hope this helps :)
6(x + 3) = 3x - 3 Given
6x + 18 = 3x - 3 Distribute the 6
6x = 3x - 21 Subtract 18 from both sides
3x = - 21 Subtract 3x from both sides
x = -7 Divide both sides by 3
5x - 2 = 3(x + 2)
5x - 2 = 3x + 6
5x = 3x + 8
2x = 8
x = 4
Jeff's solution is incorrect; his solution is incorrect because he added 3x to the left side when he should have subtracted it to cancel it from the right side.
Hope this helps.
