Answer:
x = 5
Step-by-step explanation:
Δ EAB and Δ EDC are similar by the AA postulate , so the ratio of corresponding sides are in proportion , that is
= 
, substitute values
= 
( cross- multiply )
10(x + 3) = 4(2x + 10 ) ← distribute parenthesis on both sides
10x + 30 = 8x + 40 ( subtract 8x from both sides )
2x + 30 = 40 ( subtract 30 from both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Multiply each term by 8 ( to get rid of the fractions)
we get:-
-72 = -16 - k
k = -16 + 72 = 56 answer
The answer is 6 units and 3 fourths
88 * 2 = 176 ;
88 * 3 = 264 ;
88 * 4 = 362 ;

Answer:
0.43
Step-by-step explanation:
2+3+1+1=7
7*4+28==Area of full shape
(2*4)+(1*4)=12==Area of shaded shapes
12/28=0.428571>rounded up>0.43
