Assuming x represents the length of the first side.
Use Pythagorean theorem to solve: a^2 + b^2 = c^2
Solve the quadratic equation using the quadratic formula.
At the end, you will get side lengths of #(-14 ± 34) / 4, or -12 and 5
SInce a negative triangle length is impossible, 5 is the value of x and 5 + 7 is the value of x + 7, which makes 12.
The formula for area of a right triangle is A = B H/2
After doing your work you should get. 30cm^2
An equation is something with a = sign btw and it’s C because it’s the only one with the = sign
Hey there for this one you need to know just a few trig identities and just move things around
Answer:
Hey there! Since 20 is 25% of 80, there will be 20 carrots. I hope this was helpful!
Step-by-step explanation:
Answer:
D, 8/15
Step-by-step explanation:
1/3 + 1/5
= 1(5)/3(5) + 1(3)/5(3)
= 5/15 + 3/15
= 8/15
