Answer: 3.5
Step-by-step explanation:
Pythagorean Theorem!
2squared + x squared = 4 squared
4+x=16
16-4=12
Square root of 12 is 3.4641
Answer:
25x + 10y
Step-by-step explanation:
if you replace x with 4 and y with 6, you will find out that it is equal to 160
The answer is 20
I read it wrong sorry because it was blurry
5x2=−30x−65
Subtract -30x-65 from both sides.
5x2−(−30x−65)=−30x−65−(−30x−65)
5x2+30x+65=0
Use quadratic formula with a=5, b=30, c=65.
x = −30±√−400 / 10
No solution.
To find the area of a trapezoid, it’s 1/2(base 1 + base 2) x height.
so in this case, base 1 is 16 (add 12+2+2) (the top one) and base 2 is 12 (the bottom one) and the height is 9.
you input all the values in the formula and you get 126in.
hope this helped:)
