f1×f2-f3=(-5x+4)×(-6x-5)-(-9x+2)=30x^2-24x+25x-20+9x-2=30x^2+10x-22=(5x+1)^2-23
Answer:
The answer is 3.
Step-by-step explanation:
-2x + 7 = X-2
-2(3) + 7 = (3)-2
-6 +7 = 1
1 = 1
First, let's simplify this a bit ok?
Now, as a decimal: 3.5
As percent you multiply the number by 100 % (which is 1, and you an always multiply by 1):
3.5 *100%=350 %.
Answer:
x = 55
y = 60
Step-by-step explanation:
If a quadrilateral is inscribed in a circle, then its opposite angles are supplementary. So E and G are supplementary, and H and F are supplementary.
x + 15 + 2x = 180
3x + 15 = 180 combine like terms
3x = 165 subtract 15 from both sides
x = 55 divide both sides by 3
y + 3y - 60 = 180
4y - 60 = 180 combine like terms
4y = 240 subtract 60 from both sides
y = 60 divide both sides by 4
