Answer: 70

Step-by-step explanation: To find the least common multiple for the integers 14 and 35,  we start by making a factor tree for each of the integers.

14 factors as 2 × 7 and 35 is 7 × 5. We are looking for the factors that match up.

In this case, both integers have a factor of 7.

When finding the LCM, we multiply all the factors together, but because the 7's match up, we only need to multiply by 7 once.

So we have 2 × 7 × 5 which is 70.

Therefore, the least common multiple for 14 and 35 is 70.

What is the value of x in the diagram?
dalvyx [7]

Answer:

x = 30

Step-by-step explanation:

here 50 is hypotenuse as it is opposite of 90 degree.

x and x + 10 are the two other smaller sides of a right angled triangle respectively.

using pythagoras theorem,

a^2 + b^2 = c^2

x^2 + (x + 10)^2 = 50^2

x^2 + x^2 + 20x + 100 = 2500

2x^2 + 20x + 100 = 2500

2x^2 + 20x + 100 - 2500 = 0

2x^2 + 20x - 2400 = 0

2(x^2 + 10x - 1200) = 0

x^2 + 10x - 1200 = 0

x^2 + (40 - 30) - 1200 = 0

x^2 + 40x - 30x - 1200 = 0

x(x + 40) - 30(x + 40x) = 0

(x + 40)(x - 30) = 0

either x + 40 = 0          OR x - 30 = 0

x = 0 - 40

x = -40

x - 30 = 0

x = 30

x = -40,30

since the length and distance is not measured in negative ur answer will be 30
