So solve for ?
we use commutative which is a(bc)=(ab)c or also =abc
remember that (? times 7)=1(? times7)=1 times ? times 7=? times 7=7?
and
-(? times 3)=-1(? times 3)=-1 times ? times 3=  -? times 3=-?3=-3?
so we have
8 times 4=7?-3?
7? means 7 times ? so therefor 7?-3?=7 times of ?  -3  times of ?=7-3=4 times of ? so 4?
8 times 4=4?
multiply divide both sides by 4
8=?

8*4 = 32

Now, we need to solve this:-

32 = (?*7) - (?*3)
32=8*7 - 8*3
32= 56 - 24
32 = 32

So our equation is:-

8*4 = (8*7) - (8*3)

Answer:

3 inches

Step-by-step explanation:

(14+2x) × (15+2x) = 2(14×15)

210 +30x +28x + 4x² = 420

4x² + 58x - 210 = 0

2x² + 29x - 105 = 0

2x² + 35x - 6x - 105 = 0

x(2x + 35) - 3(2x + 35) = 0

(x - 3)(2x + 35) = 0

x = 3, -35/2(not possible)

What is the sum of a 6-term geometric series if the first term is 21 and the last term is 1,240,029?
igor_vitrenko [27]
21 times x to the fifth (where x is the ratio between values) equals 1240029
1240029/21=59049
59049^(1/5)=9
so the values are 21, 21*9, 21*9^2, 21*9^3, 21*9^4, 1240029
the sum of these values is 1395030
