Answer:
Step-by-step explanation:
answer = 1/2 r + m
m = 7
r = 8
answer = 1/2 * 8 + 7
answer = 4 + 7
answer = 11
Let us try and solve it analytically. We have that the side=x+3 together with the short side=s and the diagonal=x+4 satisfy the Pythagorean Theorem. Then we have that
. This yields
which yields s^2=2x+7, hence a) is the correct answer.
Answer:
D
Step-by-step explanation:
When you have two opposite numbers on a numberline, that is, a digit that has a negative value and the same digit having a positive value, when you add them together, we would have 0.
i.e. -a + b = 0
In the above options given, the numberline that shows this particular case is the numberline in option D.
In option D numberline, the sum of -1 and +1 equals zero.
Answer:
57.1 mm^2
Step-by-step explanation:
AREA OF TOP and BOTTOM = 8+8 = 16 mm^2
AREA OF SIDES = 12+12+17.1 = 41.1 mm^2
TOTAL SURFACE AREA = 16 + 41.1 = 57.1 mm^2
