Answer:
(3x/4) + 4
Step-by-step explanation:
convert al to decimal and then add
1.25 + 0.75 +0 .4 + 2x 0.375 + 1.6
Answer:
10 cm
Step-by-step explanation:
we know that the perimeter of a rectangle= 2(l+w)
given that the perimeter is 46 cm and length is 13 cm, so by putting the values we get,
2(13+w)=46
= 26+2w=46 (opening the brackets)
= 2w= 46-26
= 2w=20
= w=20/2
w= 10 cm

It can be solved by factoring or taking the root of both sides.
x= 2 radical 3. and -2 radical 3
Factoring:
FOIL (first, outer, inner, last) method
(a+b)(c+d) = 0
ac+ad+bc+bd = 0
Zeros:
(x+a)(x+b) = 0
x+a = 0, x= 0-a
x+b = 0, x= 0-b
