Answer:
4(x+3)
Step-by-step explanation:
There are 14 girls in HR 218 because 24/12 is 2, meaning that the ratio needs to be multiplied by 2/2 in order to figure out what 7/12 is. 7/12*2/2 is 14/24, therefore there are 14 girls in HR 218.
Because it's iscosceles, angle 1 is similar size to the angle on the right leg.
∠1 = 67°
The sum of interior angles in trapezoid equals to 360°.
And because it's iscosceles, the upper angles are in the same size. We can write it as,
the sum of angles = 360°
67° + 67° + ∠2 + ∠2 = 360°
134° + 2 × ∠2 = 360°
2 × ∠2 = 360° - 134°
2 × ∠2 = 226°
∠2 = 113°
Final answer
∠1 = 67°
∠2 = 113°

Answer:
Plot the point (3, -5)
Step-by-step explanation:
Recall that the general number a+bi can be plotted on a complex plane with the x axis as the real part and the y axis as the imaginary part.
In short,
a = real part = x
b = imaginary part = y
So (a,b) = (x,y)
In this case, a = 3 and b = -5 which is how I got (3, -5).
It might help to rewrite 3 - 5i into 3 + (-5)i
