Answer:
Step-by-step explanation:
No but it is close. (4x +13x +10) factors into
(4x + 5)(x + 2)
So (x + 2) is a factor along with (4x + 5)
Answer:
Slope: 1/3; Y-iintercept: 4 y=1/3x+4
Slope: -2; Y-intercept: 4 y=-2x
Step-by-step explanation:
Hope this helps :3
if it did pls mark brainliest
Answer:
x = ± 2
Step-by-step explanation:
Given
x² = 20 ( take the square root of both sides )
x = ± 
= ± 
= ± 2
(1/3x+3)=5-x
multiply both sides by three
1x+9=15-3x
add 3x to both sides
4x+9=15
subtract 9 from both sides
4x=3
divide both sides by 4 to isolate x
x=3/4
Answer: option A is the correct answer
Step-by-step explanation:
The set of line segments that can be used is the one such that, its longest side is lesser than the semi perimeter,s[s=(a+b+c)/2] of the triangle.
If we apply this condition on the given line segments,
A) 2 cm, 8 cm, and 9 cm
s = (2+8+9)/2 = 9.5
9.5 is greater than 9cm
B) 3 cm, 6 cm, and 2 cm
s = (3+6+2)/2= 5.5
5.5 is lesser than 6. If we go on to look for the area using
Area = √s(s-a)(s-b)(s-c), it would be impossible because we would end up having square root of a negative number.
C) 5 cm, 9 cm, and 3 cm
s = (5+9+3)/2 = 8.5
8.5 is lesser than 9cm
If we go on to look for the area using
Area = √s(s-a)(s-b)(s-c), it would be impossible because we would end up having square root of a negative number.
D) 6 cm, 3 cm, and 10 cm
s = (6+3+10)/2 = 9.5
9.5 is lesser than 10
If we go on to look for the area using
Area = √s(s-a)(s-b)(s-c), it would be impossible because we would end up having square root of a negative number.
So option A is the correct answer
