Answer:
4(5j+3j) is 32j
4(3j) is 12j
5j+3j+9j is 17j
Step-by-step explanation:
Answer:
x=8,9
Step-by-step explanation:
x^2-17x+72=0
(x-8)(x-9)=0
x=8,9
This problem boils down to 5/6 - 1/4
To subtract these fractions you need a common denominator.
I'll use 12
The first fraction becomes 10/12 and the second fraction becomes 3/12
10/12-3/12 = 7/12
So Jacob is 7/12 of a foot taller than Linda.
Also note than since 12 inches = 1 foot, you could say Jacob is 7 inches taller than Linda
Slope=6 because the slope travels upwards by 6
Answer:
B.)21.4
Explanation
A(-4, 3), B(0,2), C(2,4) and D(0,-3)
AB = √(1²+4²) = √17 =4.12
BC = √(2²+2²) = √8 = 2.83
CD = √(2²+7²) = √53 = 7.28
AD = √(4²+6²) = √52 =7.21
Perimeter = 4.12+2.83+7.28+7.21 = 21.44
To the nearest tenth the answer is 21.4.
