Answer:
2(5x - 4)(x + 1)
Step-by-step explanation:
10x^2 + 2x − 8 =
First, factor out the GCF of all terms which is 2.
= 2(5x^2 + x - 4)
5x^2 factors into 5x and x.
= 2(5x )(x )
-4 factors into -4 and 1, -1 and 4, and -2 and 2. Use the set of two factors in the proper positions that will give the middle term.
= 2(5x - 4)(x + 1)
4 ft 6 in
3 ft 9 in
4 ft 11 in
-------------add
11 ft 26 in
there are 12 inches in 1 ft.....so 26 inches = (26/12) = 2 ft 2 inches
11 ft + 2 ft 2 in = 13 ft 2 in <===
Answer:
As shown in picture,
Angle CDF = Angle BDE = 54 deg (pair of opposite angles)
Angle CDB = 180 - CDF = 180 - 54 = 126 deg (BF is a diameter).
=> Arc CB = Angle CDB = 126 deg (property of angle on circle)
Hope this helps!

Step-by-step explanation:
f(x)=4x+7
y = 4x+7
4x = y-7
x = (y-7) /4
the correct answers are:
=> f`¹(x) = (x-7) /4 (a)
=> x - 7 = 4y (e)
=> (x-7) /4 = y (f)
=> x = 4y +7 (g)
