Answer:
(x − 5) (x + 4)
Step-by-step explanation:
x² − x − 20
Factor using AC method:
1 × -20 = -20
Factors of -20 that add up to -1: -5 and 4
Divide by 1 and reduce: -5/1 and 4/1
(x − 5) (x + 4)
Answer:
g(x) = 4rx + 4r - 4x - 4
Step-by-step explanation:
g(x)= -(x+1)(r-1)(-4)
Sum of interior angles in a triangle = 180
2x - 1 + 11x + 3 + 5(x - 4) = 180
13x + 2 + 5x - 20 = 180
18x - 18 = 180
18x = 198
x = 11
Answer:
Step-by-step explanation:
Let the dog walking job be x
And sales job be y
We have to form inequality by the given information:
Work a total of no more than 41 will give us
Next condition is: dog walking pays $5 and sales job pays $8 per hour and we have to earn atleast 254 it will give us
Hence,
And
Split it up into segments--
Red: 1/2(4×1) + 1/2 + 1 + 1/2 + 1/2 + 1×4 = 2+2+4.5 = 8.5 sq. units
Purple: 1/2(2×1) + 1/2 +1 + 1×4 + 1/2(2×4) + 1/2(1×4) = 1+1+4+4+2 = 12 sq. units
