Here, You need to apply "Proportionality Theorem"
According to this theorem, the ratio of components of a leg would be equal to the ratio of corresponding components of another leg.
In mathematical form,
TV/VS = TW/WU
Substitute their values,
14/6 = 21/(x+4)
14(x+4) = 21*6
14x+56 = 126
14x = 126-56
x = 70/14
x = 5
In short, Your Answer would be 5
Hope this helps!
Answer:
x = 2 or x = -2
Step-by-step explanation:
5x² - 15 = 5
⇌
5x² = 15 + 5
⇌
5x² = 20
⇌
x² = 20/5 = 4
⇌
x² = 2²
⇌
x² - 2² = 0
⇌
(x - 2)(x + 2) = 0
⇌ we use the zero product property
x - 2 = 0 or x + 2 = 0
⇌
x = 2 or x = -2
Answer:
16π in
Step-by-step explanation:
circumference formula is 2πr
so as the minute hand goes around with time it will travel 16π in or 50.27in
Answer:John's error is that he applied the transformation rule to the image instead to the pre-image.The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5). This results to (4, 5) + (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image.
