Answer:
3(7a+3)
Step-by-step explanation:
Take out 3 as a common factor.
I believe it should be B.156 square feet because in order to find the area of a square, you gotta multiply 13ft and 12ft. Once that is solved your answer should be 156.
Answer:
x=6
Step-by-step explanation:
(x*3)+4=22
Subtracting 4 from both sides:
(x*3)=18
Dividing both sides by 3:
x=6
Hope this helps!
Answer:
A. V = 1.936 cm^3
(or it could be C. V = 3.872 cm^3) **without the image, I can't be sure, but: if there are 2 congruent (identical) prisms, it might be asking for the entire volume, which would then be 2(1.936) = 3.872 cm^3
Step-by-step explanation:
I don't have the image shown, but the unit cm^3 means you're solving for volume. The formula is V = (1/2)wlh where width=w, length=l, h=height.
This simplifies to:
V = 1.936 cm^3
To solve these, basically find out how many numbers satisfy your requirment, then divide that number by 10. Simplify your fraction and you have your probability.
probability of getting a 10: 1/10
probability of getting a 5: 1/10
probability of not getting 10: 9/10
probability of getting an odd number: 5/10
probability of getting a number less than 4: 3/10
probability of getting a number greater than 7: 3/10
Hope this helps, and muchas luck on your math!
