Answer: (3x + 4y)(3x + 4y)
Step-by-step explanation: So you are supposed to "unfoil". So you would find two numbers multiplied together to make 9x^2 which would be 3x. Then you would find two numbers that can be multiplied together to get 16y^2 which would be 4y. To check your work, you do 3x times 3x. Then 4y times 4y. Then 4y times 3x plus 3x times 4y. You get 9x^2 + 24xy plus 16y^2.
Answer:
9 + 10 = 19 product is 9 x 10 = 90 9^2 + 10^2 = 181
Answer:
2 and 4
Step-by-step explanation:
This is the only one where the two angles add up to 180 degrees, aka, a straight line.
y = mx + b
The b is always the y-intercept, so that means
y = mx + b
y = 6x + 8
The answer is C. (0, 8)!
