-3.2b + 9
by adding like terms together.
Answer:
Trinomial
Step-by-step explanation:
Because it is broken up in three terms and trinomial means three terms
Answer:
y=-8x+4
y=-x-3
Step-by-step explanation:
for the first one start at 4 on the y-axis, then go down 8 and right 1
and for the second one start on negative 3 on the y-axis, then go down one and right one.
hope this helps
Answer:
See answers below
Step-by-step explanation:
Since both trinagles asre similar hence the ratio of the similar sides are equal.
From both triangles;
y + 7 = 3y - 7
y - 3y = -7-7
-2y = -14
y = 14/2
y = 7
FE = 3y - 17
FE = 3(7) - 17
FE = 21 - 17
FE = 4
AB = y'+7
AB = 7 + 7
AB = 14
Similarly
3x+20 = 5x - 80
3x -5x = -80-20
-2x = -100
x = 100/2
x = 50
<A = 3x + 20
<A = 3(50) + 20
<A = 150 + 20
<A = 170degrees
Hence x= 50 and y = 7
Answer:
D
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Since the length of the base and the height of the triangle is equivalent to the length of a side of the square, s,
area of triangle
= ½ ×s ×s
= ½s²
Given that the area of the triangle is 12.5 units²,
½s²= 12.5
Multiply both sides by 2:
s²= 12.5(2)
s²= 25
Square root both sides:
s= 5 units
(reject negative value since s > 0)
