Answer:
128
Step-by-step explanation:
You get this by doing PEMDAS. We start with parenthises and then exponet so we do 4x4 which is 16 now we have 18-16+2 so we go in order and the anwser for the first line is 4 but we have an exponet so 16
now the second line we divide 1 and 4 we get 4 and now we multiply by 1/2 and we get 2. now we have 16/2 that is our anwser and we can put that to a whole number of 128
Answer:
3.2
Step-by-step explanation:
If there are 2 secont lines intersecting inside a circle like the picture shown, then the theorem tells us that <em>"the product of 2 segments of one secant line is equal to the product of 2 segments of other secant line"</em>
<em></em>
Thus, we can say that:
x * 10 = 8 * 4
10x = 32
x = 32/10
x = 3.2
B I’m not 100% sure but I think
60*80-10*16 if it's regular area and not surface area
