1170 is actually incorrect.
You have six congruent triangles. Each has a height of 26 and a base of 30.
So one triangle will have an area of (26 * 30) / 2 = 390.
We have six triangles, so the area will be 390 * 6 = 2340
The answer to this is 229.183°
I assume you mean x squared in the first equation
Because both are equal to y, they are equal to each other so x + 5 = x^2 +3
If we then move everything over to one side, we get x^2 - x - 2 = 0
Then factorise it to (x-2)(x+1) = 0
And solve both parts separately
x + 1 = 0
x = -1
x-2 = 0
x = 2
Sub both values into the simplest equation in this case y=x+5
to get y = 4 and y = 7
Answer: Y = 2x - 9
Step-by-step explanation:
You need to get y by itself, that would be adding, subtracting or dividing anything around it.
2y = -18 + 4x
Y = 2X - 9
