Answer:
16c^2+56c+49
Step-by-step explanation:
(4c+7)^2 means (4c+7)(4c+7)
Use foil to multiply: 4c(4c)+4c(7)+7(4c)+7(7)
Simplifying : 16c^2+28c+28c+49
16c^2+56c+49
Answer:
(-5,5)
Step-by-step explanation: add the equations in order to solve first variable. put the value in the other equations to solve the remaining variables- math way
3(K+D) is the formula you would use.
The answer is ( 7, -10)
We need a right triangle width base 12 and height 5.
By Pythagorean theorem, the hypotenuse is sqrt( 5^2 + 12^2) = sqrt( 25 + 144) = sqrt(169) = 13
Holly is at (2,2), so we start there.
We move 5 squares to your RIGHT on your graph paper.
That is (7,2)
From there we move 12 squares straight down.
That is at (7,-10), which is where Joe is in the 4th quadrant.
