Answer:
the answer is b
Step-by-step explanation:
the x axis is left and negative units would go to the left
the y axis is up and down so positives would go up
10×6 tens in unit form is written
10×6 tens= 60 tens= 600 units
1. Factor by grouping: (16x^2+20x)(20x+25)
2. 4x(4x+5)+5(4x+5)
3. (4x+5)(4x+5)
4. (4x+5)^2
Answer:
≈ 50.7 cm²
Step-by-step explanation:
The area (A) of Δ XYZ is calculated as
A =
bh ( b is the base and h the perpendicular height ), that is
A =
× XY × YZ
Calculate YZ using the tangent ratio in the right triangle
tan40° =
=
=
( multiply both sides by 11 )
11 × tan40° = x , that is
YZ ≈ 9.23 cm
Thus
A =
× 11 × 9.23 = 5.5 × 9.23 ≈ 50.7 cm² ( to 3 significant figures )
Answer:
2 solutions
Step-by-step explanation:
The graphed lines intersect at two points and those two points would be your solutions.
