Answer:
Step-by-step explanation:
1. Expand by distributing sum groups.
2. Expand by distributing terms.
3.Expand by distributing terms.
4. Remove parentheses.
5. Collect like terms.
6. Simplify.
Thus. the answer is,
(x+1)(x-4)-(x-2) = 0
x²-4x+x-4-x+2 = 0
x²-4x-2 = 0
/\ = (-4)² - 4*1*(-2)
/\ = 16 + 8
/\ = 24
x = (-(-4)+/- \/24) / 2
x = (4+/-\/4*6)/2
x = (4+/-2\/6)/2
x = 2+/-\/6
x' = 2+\/6
x" = 2-\/6
Answer:
646+738=1380
356+467=820
Step-by-step explanation:
27.5/100=11/x
11 x 100 = 27.5x
1100=27.5x
1100/27.5=x

Answer:
1.95
Step-by-step explanation:
area = (1/2 ×1 ×1 )×3 = 1.5 ( for sides)
area = ( 1/2 ×1 ×0.9) = 0.45 for base
area =1.5+0.45 = 1.95
