Answer:
1.88
Step-by-step explanation:
A farmer sells 9.4 kilograms of pears and apples
4/5 of the total weight is pears while the rest is apple
Let x represent the number of apples
9.4= 4/5 ×9.4 + x
9.4 = 0.8×9.4+x
9.4 = 7.52+ x
9.4-7.52= x
1.88= x
x= 1.88
Answer:
A = (2x² + 4x + 1) (8 − x)
A = -2x³ + 12x² + 31x + 8
Step-by-step explanation:
W = 2x² + 4x + 1
L = 8 − x
Area is width times length.
A = (2x² + 4x + 1) (8 − x)
If you wish, you can simplify with distribution.
A = 8 (2x² + 4x + 1) − x (2x² + 4x + 1)
A = 16x² + 32x + 8 − 2x³ − 4x² − x
A = -2x³ + 12x² + 31x + 8
Answer:
45
Step-by-step explanation:
Every Triangle has 180 degrees.
x + 8x + 3x = 180
12x = 180
x = 180/12
x = 15
Angle K = 3x
K = 3 * 15
K = 45
