Answer:
9) (68 + 160)/2 = 114°
10) 80/2 = 40°
11) 105 x 2 = 210°
12) 80 x 2 = 160°
13) (360 - 180 - 108)/2 = 36°
14) (360 - 69 - 95)/2 = 98°
120/5 = x-2(x+3)
24= x^2+x-6
subtract 24 on both sides
this is so you know where the next stuff comes from
A b c
(1)x^2+(1)x-30 now its quadratic ( i prefer factoring but you can apply quadratic formula to it )
for factoring you multiply A by c and get -30 and see what multiplies to get -30 and adds to get 1 you get -5 and 6
you set that to x-5 and x+6 (this is only if A =1 )
you get x=5 and x=-6 due to the product property (x-5=0 and x+6=0 solve for x how i got it )
your answer can be negative so x is equal to 5
5*(5-2)*(5+3)
5*3* 8
L*W*H
width is 3 Height is 8
awnser is 8 give brainliest plox
Answer:
x = -2.75
Step-by-step explanation:
:D
14 - 3 = 11
11 / -4 = -2.75
Answer: 63.59cm²
Step-by-step explanation:
The area covered by the pitch will be gotten by finding the value of the area of the circle and this will be:
Area of q circle = πr²
where,
π = 3.14
r = radius = diameter/2 = 9cm/2 = 4.5cm
Area = πr² = 3.14 × 4.5²
= 3.14 × 20.25
= 63.59cm²
Therefore, the area covered by the pitch is 63.59cm²
