This is a Pythagorean theorem problem. the ladder is 12 from the building and needs to teach 14 ft up. the length of the ladder it's the hypotenuse
12²+14²=c²
144+196=c²
340=c²
c=√340 or about 18.5 ft
Answer:
6x - 4
Step-by-step explanation:
Cross out the 3 in the denominator and the 9, which simplifies to 2 times 3x, which is 6x. For the second part, cross out 3 in the denominator and -6, which becomes 2 times (-2), which is -4.
X = 3 my answer needs to be 20 characters
Answer:
x = 12
Step-by-step explanation:
Step 1: Write quadratic
x² - 24x + 144 = 0
Step 2: Factor
(x - 12)(x - 12) = 0
Step 3: Find roots
x - 12 = 0
x = 12
Answer:
x = -2
Step-by-step explanation:
Multiply both sides by 3 to get rid of the fraction:
x - 10 = -12
Add 10 to both sides:
x = -2
