Subtract 7a from both sides giving you 10=-5a and divide everything by 5. This gives you a=-2
Answer:
6x^2 (3x^2 - 2)
Step-by-step explanation:
18x^4 - 12x^2
6x^2 (3x^2 - 2)
Answer:
11a. 15x + 6
11b. x + 8 < 16 or x + 8 - 16
12. 3x + 15 + 5x = 8x + 15
13. 7x + 31
Step-by-step explanation:
Answer:
(A)29 cubic inch
Step-by-step explanation:
Diameter of the Cone =4 Inches
Height of the Cone =7 Inches
Volume of a Cone 
First, we determine the radius, r.
Radius=Diameter/2=4/2=2 Inches
Therefore:
Volume of one paper cone 
=29.32 cubic inch
=29 cubic inch (to the nearest cubic inch.)
