Lets take a look at the options first.
option 1 and option 4 are not possible as (8x) (8x) would give us 64x^2, which is not what we want.
we’re left with option 2 & 3. when expanded, option 2 will look like :
16x^2 - 40x - 10x + 25
= 16x^2 - 50x + 25
however, we do not want the 50x. so the answer is option 3, (4x-5) (4x+5)
if you don’t want to find the answer using expanding, there is also another method of expanding.
(a+b)^2 = a^2 - b^2
in this case, 16x^2 will be a^2 and 25 will be b^2. not sure whether you’ve learn this but yea.
Vertical angle is when opposite angles meet in the middle of two intersecting lines (share the same vertex). They are equal to each other too.
Hope this helps! :)
Answer: 352/105
Step-by-step explanation:
Diameter of the circular disk is
(2−x2)−x2
so that the radius of the disk is the diameter divide by 2
(2−x2−x2)/2.
Integrating V at 1 and -1, we get
V =Z 1−1A dx =Z 1−1π(1 − x2)2
dx = π(x −2/3x3 +1/5x5)1−1
=16/15π
= 352/105
we are given
6 × 8 = 48
we know that
commutative property of multiplication:
now, we will verify each options
option-A:
we have
6 × 8 = 48
now, we can find it's commutative
so, we get
8 × 6 = 48
so, this is TRUE
option-B:
we have
6 × 8 = 48
now, we can find it's commutative
so, we get
8 × 6 = 48
so, this is FALSE
option-C:
we have
6 × 8 = 48
now, we can find it's commutative
so, we get
8 × 6 = 48
so, this is FALSE
Answer:
6
Step-by-step explanation:
28 divided by 4 = 6
