Answer:
Step-by-step explanation:
We can solve this with the help of Pythagoras theorem.
- => (√50)² = x² + x²
- => √50 x √50 = x² + x²
- => 50 = 2x²
- => 25 = x²
- => x = 5
Hence, the value of x is 5 units.
Answer:
1256 cm
Step-by-step explanation:
First we must find the perimeter, because the perimeter is equal to 1 revolution.
The perimeter of any circle is Pi(Diameter)
3.14*20
62.8 cm is the perimeter of the bike wheel.
Because the perimeter is basically a revolution, we can multiply 62.8 by 20 to get:
1256 cm
Answer:
#1= 5x5=25
25x the amount of squares= 25x6= 150cm^2
#2= 1.5x2.6= 3.9ft.
3.9xamount of right angle triangles= 3.9x8=31.2ft^2
(^2 means squared)
Answer:
A) f(x) = x^2 +8(x+2)
Step-by-step explanation:
We will start by putting y=0
0 = x^2+8(x+2) -Apply distributive property
0 = x^2+8x+16
0=(x+4)(x+4)
0=x+4, 0=x+4
x=-4
There is only one zero, and that is x=-4
