Im pretty sure the answer is 92.0 becauese
if you do 10.5x3.5 5x5=25 5x0+2=7 5x1=5 so that will be 57.5 then your going to do 3x5=15 3x0+1=4 3x1=3 that equals 34.5 then your going to add 57.5 +34.5
= 92.0
Answer:
11) x = 45
12) x = 30
Step-by-step explanation:
11)
3x + x = 180
4x = 180
x = 45
12)
4x = 5x - 30
4x - 5x = -30
-x = -30
x = 30
The veretx is normally the minimum value
hack:
for f(x)=ax²+bx+c
the x value of the vertex is -b/2a
so
f(x)=1x²-16x+71
x value is -(-16)/(2*1)=16/2=8
find f(8) to find y value of vertex
f(8)=8²-16(8)+71
f(8)=64-128+71
f(8)=7
the vertex is (8,7)
the minimum value is 7

Answer:
C. 72
Step-by-step explanation:
So imagine every straight line you see equals to 180 degrees, so given one side of the angle...180 - 108 = 72
