B Is the first one and I think 10 is A
Answer:
y = 8
x = 11.3
option 2
Step-by-step explanation:
We can recognize this right triangle as a special triangle, a 45° - 45° - 90° triangle more specifically. This triangle would be isosceles because the two base angles are both 45°. Since the triangle is isosceles, we can say that the legs are congruent, so y = 8. In a 45° - 45° - 90° triangle, the hypotenuse is √2 times the legs. To find x, we can set up the equation:
8 * √2 =x
x = 8√2 or about 11.3
Answer:
x=40
Step-by-step explanation:
subtract first then multiply
7*38=7x-14
move terms 266=7x-14
calculate-7x=-14-266
divide both sides by -7 (-7x=-280)
solution x=40
Answer:
200
Step-by-step explanation:
i multiplied the answer choices by the fractions and 200 was the one that checked out
Answer:
16,767
Step-by-step explanation:
Geometric sequence formula: an = ar^n-1
Now, we just plug in the values.
an = 23(3)^7-1
an = 23(3)^6
an = 23(729)
an = 16,767
