Answer:
<u>(3w + 7)² or (3w + 7)(3w + 7)</u>
Step-by-step explanation:
<u>Identity</u>
- a² + 2ab + b² = (a + b)² = (a + b)(a + b)
<u>Solving</u>
- 9w² + 42w + 49
- (3w)² + 2(3w)(7) + (7)²
- <u>(3w + 7)² or (3w + 7)(3w + 7)</u>
Answer:
Option b
Step-by-step explanation:
According to the property of rhombus at Centre it have 90°
So,
Hope this helps u ^_^
Answer:
c. (A + B)^2-A^2 + 2AB + B^2
Step-by-step explanation:
Given that:
a.
(A-B)^2 = A^2 - 2AB + B^2
If and only if AB = BA
Then;
(A-B)^2 = (A -B ) (A - B)
(A-B)^2 = A^2 - AB-BA + B^2 (FALSE)
b.
(AB)^2=A^2B^2
on true if any only if AB =BA
(AB)^2= (AB) (AB)
c.
(A+ B)^2 = A^2 + 2AB + B^2
(A+ B)^2 = (A + B) (A+B)
(A+ B)² = A × A + A × B + B × A + B × B
(A+ B)^2 = A^2 + A*B + B*A + B^2
This is true
I believe it is 8,000 grams :).
Answer:
<h2>
The answer is A</h2><h2>A. S = 1/2p - L</h2>
Step-by-step explanation:
Step one:
given the perimeter function
P = 2S + 2L
we are expected in this problem to change the subject of the formula to S
Step two:
firstly, let us isolate the term that has S
2S=P-2L
divide both sides by 2
2S/2= (P-2L)/2
S=P/2-L
S = 1/2p - L
