Answer: x²+8x+16
Step-by-step explanation:
(x+4)^2=(x+4)(x+4)
Now use distributive property to expand (x+4)(x+4):
(x+4)(x+4)=x²+4x+4x+4(4)
x²+4x+4x+4(4)=x²+8x+16
Two musician will need 12 minutes to play the song
Answer:
Question one = 35a - 15
Question two = 9
Step-by-step explanation:
Distributive property means to multiply all the numbers inside the parenthesis
by the outside number. 5 x 7a equals 35a and 5 x 3 = 15.
35 x 9 - 315 - 15 = 300
A = 9
V = (8x7) / 17
v = 56 / 17
v = 3.294
v = 3.3
Answer:
The fraction of brownies with both white frosting and small red hearts is not given. And also the total number of brownies made is not given too.
Therefore, the number of brownies that have both white frosting and small red hearts on them cannot be determined
Step-by-step explanation:
Given;
1. You put 1 white frosting per 3 of the brownies
2. You put 1 small red hearts per 4 of the brownies
Fraction of brownies with;
White frosting = 1/3
Small red hearts = 1/4
The fraction of brownies with both white frosting and small red hearts is not given. And also the total number of brownies made is not given too.
Therefore, the number of brownies that have both white frosting and small red hearts on them cannot be determined
For example:
Assuming that;
The fraction of brownies with both white frosting and small red hearts = 1/12
The total number of brownies baked = 36
The number of brownies with both white frosting and small red hearts = 1/12 × 36 = 3 brownies.
