Answer:
B and D
Step-by-step explanation:
A simplifies to a linear equation
C is a cubic
The other 2 are quadratic and can be solve using the formula
Answer:
2x + 9y + 5
Step-by-step explanation:
Combine like terms:
(6x - 4x) + (4y + 5y) + 5
2x + 9y + 5
Answer:
Step-by-step explanation:
Let the other number = x
x + 40 = 73
Subtract 40 from both sides
x + 40 - 40 = 73 - 40
x = 33
180 m
Step-by-step explanation:
Information given:
- length of Mrs. Flores' garden= 20 m
- width of Mrs. Flores' garden = 15 m
- Scale factor = 3
Since scale factor is 3, to get measurements of sides Mr. Sosa's garden, sides of Mrs. Flores's have to be multiplied by 3. Hence,
- length of Mr. Sosa's garden= 3×20= 60 m
- width of Mr. Sosa's garden= 3×15= 45 m
Diagonal of a rectangle = √length²+width²
Let Diagonal = D,
D= √60²+45²
=√3600+2025
=√5625
=75 m
If Mr. Sosa cut his garden diagonally,
perimeter= length+width+diagonal
=60+45+75=180 m
Answer:
4250
Step-by-step explanation:
0.13 = 13%
1000×0.13=130
130×25= 3250 + 1000 = 4250
What I did:
You have to turn the percent to a decimal first
Then multiply the decimal by the first investment amount (1000)
then multiply that by the years that you have before retirement
You add that amount plus the 1000 you have started with
