Jamal's score is 80
<u>Explanation:</u>
Given:
Number of questions = 100
Let w be the number of wrong answers
Let r be the number of right answers
According to question,
r = 4w
r + w = 100
Solving both the equations we get:
4w + w = 100
5w = 100
w = 20
If w = 20 then r = 4 X 20 = 80
Therefore, Jamal's score is 80
Lets x = width
length = x + 4 (4 meters longer than wide)
A = L * W
192 = x ( x +4)
192 = x^2 + 4x
x^2 + 4x - 192 = 0
(x +16)(x-12) = 0
x - 12 = 0, x = 12
x + 16 = 0, x = -16
so width x = 12
length = 12 + 4 = 16 (4 meters longer than wide)
answer. J

Step-by-step explanation:
yes the are similar because of AA Theorem
EAB is similar to ECD
Answer:
x = 0.5
Step-by-step explanation:
2(2x-1)=3
2(2x)+1=3
-1 -1
2(2x)=2 2x2=4
4x=2
4÷4 Cancels out the 4 in X
2÷4=0.5
Therefore
x = 0.5
