Answer:
r = 7 q - 34
Step-by-step explanation:
Solve for r:
-34 + 7 q - r = 0
Subtract 7 q - 34 from both sides:
-r = 34 - 7 q
Multiply both sides by -1:
Answer: r = 7 q - 34
Answer:
<1=33, <2=90, <3=57
Step-by-step explanation:
Lines A and B are parallel lines. Find the measures of angles 1,2, and 3.
Ab = (7x-6) → b = (7x-6)/a (1)
bc = (12-2x) → b = (12-2x)/c (2)
Since (1) = (2) → (7x-6)/a = (12-2x)/c OR a/c = (7x-6)/(12-2x) (3)
Multiply both numerators of (3) by the SQUARE of their respective denominators;
(a*c²)/c = (7x-6)(12-2x)²/(12-2x)
Now simplify:
ac = (7x-6)(12x-2x) or ac = -14x² + 96x - 72
Answer:
(8a + 3)(a + b + c)
Step-by-step explanation:
8a^2 + 8ab + 8ac + 3a + 3b + 3c =
= 8a(a + b + c) + 3(a + b + c)
= (8a + 3)(a + b + c)
Answer:
50 cm squared.
Step-by-step explanation:
All you need to do is multiply the 5 (which is the height) times 10 (which is the base).
The volume of a parallelogram is base times height.
so, 5 times 10 = 50
