12/13 would be your answer if you were to simplify your answer
Answer:
Step-by-step explanation:
Angle JKL is similar to angle PQR. This means that the ratio of the length of each side of ∆JKL to the length of the corresponding side of ∆ PQR is constant. Therefore,
JK/PQ = KL/QR = JL/PR
Therefore,
x/28 = 38/42
Cross multiplying, it becomes
x × 42 = 28 × 38
42x = 1064
Dividing the left hand side and the right hand side of the equation by 42, it becomes
42x/42 = 1064/42
x = 25.33 rounded up to the nearest 2 decimal places.
Answer:
1.2 * 10 ^6
Step-by-step explanation:
0.0000012
Move the decimal 6 places to the right
The 6 becomes the exponent in
a* 10^b a must be a number 1 or greater but less than 10
b is the the number of places the decimal moves (+ to the right, - to the left)
000001.2
Then the number becomes 1.2 * 10 ^6
A= 1/2 bxh because if you are trying to find area you have to use the the formula A=1/2 bxh
Pretty sure you gotta add 8x to 2x
