Answer:
-90
Step-by-step explanation:
Answer:
24 mm
Step-by-step explanation:
Since it is a right triangle, we can use Pythagorean theorem
where a and b are the legs, and c is the hypotenuse.
We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.
Solve the exponents
Now, solve for b. To do this, get b by itself.
First, subtract 100 from both sides
Take the square root of both sides
b=24
So, the other leg is 24 mm

I took the Quiz
Find the two numbers, and their equations
Answer:
when x= 2 the corresponding y value is 6, according to the point 2,6
Step-by-step explanation:
Hey there!!
( a ) 1 + 3/x²-1 = 2/x-1
x²-1+3/x²-1 = 2/x-1
x²+2/x²-1 = 2/x-1
Note : we can write x²-1 as (x-1)(x+1)
I wrote this with the identity a²-b² = (a+b)(a-b)
x²+2/(x-1)(x+1) = 2/x-1
Multiplying (x-1)(x+1) on both sides
x²+2 = 2(x-1)(x+1) / (x-1)
x²+2 = 2(x+1)
x²+2 = 2x+2
x²-2x = 0
x(x-2)=0
x=0
x-2=0
x=2
x = 0 and 2
( b ) ( √x+3 ) - 1 = x
√x+3 = x+1
x+3 = ( x+1)²
x+3 = x²+2x+1
x+3-x²-2x-1=0
-x+2-x²=0
-x²-x+2=0
x = -b plus or minus √b2 -4ac / 2a
x = -1 plus or minus √ 1 + 8 / 2
-1 plus or minus √9 / 2
-1 plus or minus 3/2
-1 +3 / 2
x = 1
-1 - 3 / 2
-4/2
x = -2
negative cannot be a value
Hence, the answer is
x = 1
Hope my answer helps!
