Answer:
20 cm
Step-by-step explanation:
We can use ratios to solve
We know x = 7 since they are of equal length
x x+7
----- = -------
10 y
7 7+7
----- = -------
10 y
Using cross products
7y = 14*10
7y = 140
Divide by 7
7y/7 = 140/7
y = 20
Answer: 10x³
<u>Step-by-step explanation:</u>
n=0 1
n=1 1 2 1
n=2 1 3 3 1
n=3 1 4 6 4 1
n=4 1 5 10 10 5 1
The second term of the expansion is: 5(a)³(b)
= 5(x)³(2)
= 10x³
Answer:
y = -2x - 5
Step-by-step explanation:
Let the equation if the line be y = mx + c
since the line is parallel to y = -2x - 8, their gradients/slope must be the same (aka m = -2)
sub (-4, 3):
3 = -2(-4) + c
c = -5
therefore, the equation of the line is y = -2x - 5
