Answer:
22
Step-by-step explanation:
Through the distributive property, we know to multiply both numbers in the parentheses by 7. This gives us 7(40) + 7(2). Next, we have to simplify by multiplying the terms out. This gives us 280 + 14. Finally, we add and get a sum of 294. However, the question only asks for the distribute step. Therefore, your answer is B. 7 x 40 + 7 x 2.

To make a line parallel to another it must have the same slope
Given that we need to find a line parallel to y=5x-3
It must also have a slope of 5
y=5x+a
Since it passes through (-2,-4)
(-4)=5(-2)+a must be true
so a=6
y=5x+6 is the answer
1)1.10w+2.35(172-s)=294.20
When you solve
1.10x+2.35(172-x)=294.20 solve for x
X water=88
S=172-88=84
2)2t+4(40-f)=100
When you solve
2x+4(40-x)=100 solve for x
X=30 for t
40-30=10 for f
Hope it helps
Answer:
see explanation
Step-by-step explanation:
To convert from polar to rectangular coordinates
that is (r, Θ ) → (x, y), then use
x = r cosΘ and y = r sinΘ
here r = 3 and Θ = , hence
x = 3 cos()
= 3 cos()
= 3 × =
y = 3 sin()
= - 3 sin()
= - 3 × = -
(3, ) → (, - )
