Answer:
AB = 21 and DE = 23
Step-by-step explanation:
Given 2 intersecting chords inside the circle then
The products of the measures of the parts of one chord is equal to the products of the measures of the parts of the other chord, that is
x(x + 13) = (x + 10)(x + 1) ← distribute parenthesis on both sides
x² + 13x = x² + 11x + 10 ← subtract x² + 11x from both sides
2x = 10 ( divide both sides by 2 )
x = 5
Hence
AB = x + 10 + x + 1 = 2x + 11 = (2 × 5) + 11 = 10 + 11 = 21
DE = x + x + 13 = 2x + 13 = (2 × 5) + 13 = 10 + 13 = 23

Answer: x=-2 Y=1
Step-by-step explanation: You convert the first equation to slope form then you take the second equation, so 3x+3y=-3 and you plug in the Y. So this would be 3x+3(-3/4-1/2)=-3. Then you would solve that equation and get the answer 3x-9/4x-3/2=-3. Now you combine like terms to get the answer 3/4x-3/2=-3 and you add 3/2 to both sides of the equation which leaves you with 3/4x=-3/2 now you solve for x and get -2. Now to find the y you take the first equation, that you converted to slope intercept form y=mx+b, and you plug in the x. Which would give you the problem, y=-3/4(-2)-1/2 then you get y=3/2-1/2 and you combine like terms to get the answer y=1
(x²+4)(x²+4) =x^4+8x²+16
B. x4 + 8x2 + 16
Answer:
-x+4
Step-by-step explanation:
given that
(x^3-4x^2+7x-28)÷(x^2+7)
or
first (x^2+7) × -x = -x^3-7x
so (x^3-4x^2+7x-28) + (-x^3-7x) = -4x^2-28
agian (x^2+7)×(4) = 4x^2+28
so, (-4x^2-28) + (4x^2+28) = 0
