(7/2b - 3) - (8 + 6b)
= 7/2b - 3 - 8 - 6b
= 7/2b - 6b - 11
= -5/2b - 11
In short, Your Answer would be Option A
Hope this helps!
Answer:
x = 32
Step-by-step explanation:
Since all sides of the triangle are congruent then the triangle is equilateral.
The angles of an equilateral triangle are congruent with measure of 60°
Equate
2x - 4 = 60 ( add 4 to both sides )
2x = 64 ( divide both sides by 2 )
x = 32
We have 26 - 18 = 8; 34 - 26 = 8; 42 - 34 = 8; (an arithmetic progression)
We use the formula an = a1 + (n-1)x8 (the explicit formula)
So, an = 18 + (n-1)x8 ;
Then, an = 8n + 10;
Finally, a52 = 8x52 + 10 = 426 (the 52nd term);
7 981 943 000 Millimeters
V = (1/2) area of cross-section times length.
Note: I will use L in place of x to represent the length of the prism.
In short, V = (1/2)*b*h*L.
To find the surface area, use
A = bh + 2Ls + Lb
Volume given to be 15, 510.
Part (a) set up:
15, 510 = (1/2)(60)(11)L
Can you finish? Just solve for L to find your x-value.
Part (b) set up:
To answer part (b), you must find the value of L in part (a).
A = (60)(11) + 2L(61) + L(60)
Understand? Take it from here.
