X=-6
3(-6)-2y=10
-18-2y=10
2y=10+18
2y=28
Y=28/2
Y=14
Answer:
272 cm
Step-by-step explanation:
In order to calculate surface area, you need to find each individual rectangle. Four sides of the rectangle will be your length times height, so 14*4 or 56 cm. As for the other two sides, they would be height times width, so 4*6 or 24 cm. The four sides would add up to 224 cm and the other two would be 48 total. When you add all six sides together, you get 272 cm.
32^(2c)=8^(c)+7
2^10c=2^3c+21 im gonna assume 7 is in the exponent
10c=3c+21
7c=21
c=3
Answer:
A is 1 in 100 and b is 1 in 25
Step-by-step explanation:
there are 10 digits (1, 2, 3, 4, 5 ,6 ,7 ,8 ,9, 0).
that gives you a 1 in 10 chance but there are 2 and to get both of them, you do 1 in 10 x 1 in 10 which is 1 in 100. if you know that they are both even, this limits it to a 1 in 5 twice, 1 in 5 x 1 in 5 is 1 in 25.
