Remember that angles across from each either are equal. I say across from each other but I know that’s hard to understand look at the image I attached, I am referring to yellow angle. See how the yellow angle and the two w’s form a straight line, it’s draw in red in my image. A straight line is 180. So 76+2w=180 Solve it by isolating the variable w. Subtract 76 from both sides. 2w=104 divide both sides by 2. w=52

The first steps in writing f(x) = 4x2 + 48x + 10 in vertex form are shown. f(x) = 4(x2 + 12x) + 10 = 36 What is the function wri

Answer:

f(x) = 4(x + 6)² – 134

Step-by-step explanation:

To write an equation in vertex form, we first factor out the GCF of the first two terms. For 4x² and 48x, this is 4:

f(x) = 4(x²+12x)+10

Next we complete the square. The value of b inside parentheses is 12; we take half of that and square it:

(12/2)² = 6² = 36

We add this inside parentheses. However in order to preserve equality, we must subtract this value as well. Since the terms inside parentheses are being multiplied by 4, we multiply the 36 we subtract by 4 as well:

f(x) = 4(x²+12x+36)-4(36)+10

Simplifying, we have

f(x) = 4(x²+12x+36)-144+10

Combining like terms,

f(x) = 4(x²+12x+36)-134

Next we write the trinomial in parentheses as a perfect square:

f(x) = 4(x+6)²-134
