Answer:
A. 7√3
Step-by-step explanation:
The side length ratios in a 30°-60°-90° triangle are 1 : √3 : 2. Here, the shortest side is 7, and x is the next-longer side.
x = 7√3
Answer:
x = -2
Step-by-step explanation:
y= -4x - 2
/ -4. /-4
x = -2
2d^5(3d^3)
=2d^5*3d^3
=2*d^5*3*d^3
=(2*3)*(d^5*d^3)
=6*d^8
Answer: =6d^8
Answer: " y = 21 " .
____________________________________________
Cross multiply:
______________________________
(2y)(4) = 7(y + 3) ;
8y = 7y + 21
Subtract 7y from each side of the equation;
8y - 7y = 7y + 21 - 7y ;
y = 21 .

You're told that
(the sum of the first 16 terms in the sequence, presumably). Well, we know that
Recall that
so that we have
So we get
