Answer:
3y3(x2 + 4)(x + 2)(x -2)
Step-by-step explanation:
3x4y3– 48y3.
= 3y3(x4 – 16).
= 3y3[(x2)2 - 42].
= 3y3(x2 + 4)(x2 - 4).
= 3y3(x2 + 4)(x2 - 22).
= 3y3(x2 + 4)(x + 2)(x -2).
Answer:
a). Point A
b). 90°
c). Anticlockwise
Step-by-step explanation:
As it's clear from the picture attached,
Triangle XYZ has been rotated about a point A to form an image X'Y'Z'.
Angle of rotation is 90° about a point A.
a). Point which is the center of the rotation → point A.
b). Angle of rotation → 90°
c). Direction of rotation → Anticlockwise
Every positive real number has TWO<span>square roots; One is positive and one is negative. They are opposites of each other. </span>
10 is a square root of 100 because (10)(10) = 100, and ̶ 10 is also a square root of 100 because ( ̶ 10)( ̶ 10) = 100.
In general, “a” is a square root of “b” if a² = b, where “a” is a real number and b ≥ 0.
In conclusion:
<span> √(100) = </span>10<span> (the </span>positive<span> square root of 100) </span>and<span> </span>
<span> ̶ √(100) = ̶ (10) = </span>̶ 10<span> (the </span>negative<span> square root of 100)</span>
Answer:o
Step-by-step explanation:
Answer: 91
Step-by-step explanation:
the equation to find the area of a trapezoid is as follows:
A = (a+b)/2h
So A = 6+20 which is 26
then you divide 26 by two which gives you 13, then multiply by 7
