Answer:
ans: -4( x-3 )( x-4 ) I.e -4( x² + x - 12 )
Step-by-step explanation:
as per question
1- (2x-7)²
= (1 + 2x - 7)(1- 2x + 7)
= ( 2x - 6)(-2x +8)
= -4(x-3)(x+4)
If we can match teh bases we can solve
because if x=x and xᵃ=xᵇ, we can conclude that a=b
16=2⁴
32=2⁵
rememeber that




2=2 so we conclude that 4(3x+2)=5(-2x-7)
4(3x+2)=5(-2x-7)
expand/distribute
12x+8=-10x-35
add 10x both sides
22x+8=-35
minus 8 both sides
22x=-43
divide both sides by 22
x=-43/22
-2x + 8 = -4x + 1
- 1 -2x
7 = -6x
—
-6x
7/-6 or -7/6
Answer:
√200
Step-by-step explanation:
An irrational number is a number that can not be represented as a fraction
√81 = 9 = 9/1
√-16 = 4i
√-64 = 8i
√200 = ~14.14213
The numbers given in the question are 2/5, 4/9 and 3/7. We have to take them to decimal form for arranging the numbers in increasing order.
2/5 = 0.40
4/9 = 0.44
3/7 = 0.43
Then, the increasing order of the numbers would be
2/5 < 3/7 < 4/9
I hope the answer has helped you.
