A. 3
explanation:
3(2)-3
6-3
3
Answer:
Step-by-step explanation:
1.Trinomial(The definition of a trinomial is a math equation that has three terms which are connected by plus or minus notations)
2.Nope because the highest degree term is on a second place(should be on first)
3.Yes
4.Yes
5.Yes
6.Yes
7.No,-3
8.Neither odd nor even
9.Neither odd nor even
Answer:
y=4x+3 + 2x+13 solve for y
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let base be b, height be h
h = 7+b or we can say that b = h -7
A = 15 cm²
General formula for area of a triangle
A = b · h
Substitute what we know to find the height h
15 = (h-7) · h
15 = h² -7h
0 = h²-7h -15
h = (7 ±√49 + 4·1·15)/2
h = (7 ±√109)/2
h ≈ -1.72 reject this solution because height cannot be negative
h ≈ 8.72 cm
Answer:
x = 125
Step-by-step explanation:
all of the angles in a triangle must add up to 180, so 25 + 30 + x = 180. you can subtract 25 and 30 from both sides and you are left with x = 125.
hope it helps!
