9h^2+42h+49
no common factors
trial and error
try first term and last term
all sings are positive since last term and middle terms are possitive
factor leading term and coeficient and try those
9=3*3
49=7*7
(3h+7)(3h+7)
9h^2+21h+21h+49
9h^2+42h+49
true
(3h+7)(3h+7)=(3x+7)^2
answer is (3h+7)^2
answe ris ths second one
Use doubling and halving to solve. So halve 12 and double 50. Then solve. 6*100=600
Answer:
x-intercept: (-2,0); y-intercept: (0,4)
Step-by-step explanation:
First, focus on the y-axis. This axis is described by the equation x = 0. From the graph we see that the line crosses the y-axis at (0,4). This is the y-intercept.
Next, focus on the x-axis, which is described by y = 0. The line crosses the x-axis at (-2,0). This is the x-intercept.
