13. (a-b)^2=a^2-2ab+b^2
B is the answer
14. B is the answer
( x+9)(x-3)= x^2+6x-27
15. B is the answer
(x+6)(x-5)=x^2+x-30
16. D is the answer
(x-6y)(x-4y)=x^2-10xy+24y^2
17. C is the answer
(2x+5)(3x-4)=6x^2+7x-20
18. B is the answer
(5x+7)(x-2)=5x^2-3x-14
The answer would be 36. Why?
Because in the equation we would need to do (x + 6)(x + 6) to get a perfect square trinomial.
And 6 * 6 is 36.
So the whole equation would be: x^2 + 12 + 36.
Hope this helped! c:
Answer: 32
Step-by-step explanation:
He picked 30, right? Ok, so, after picking the peaches, he gave 10 of them to his granny. Then he picked 12 more peaches.
30-10=20
20+12=32
X^2+ y^2=109
x 2 + y2 = 109
Step 1: Add -y^2 to both sides.
x 2 + y2 + − y2 = 109 + − y2
x 2 = − y2 + 109
Step 2: Take square root.
x = − y2 + 109 or x = − − y2 + 109
Answer:
x = − y2 + 109 or x = − − y2 + 109 CALCULATE IT
Solve for Variable
x-7=1/3y^2
x − 7 = 1
3 y2
Step 1: Add 7 to both sides.
x − 7 + 7 = 1
3 y2 + 7
x = 1
3 y2 + 7
Answer:
x = 1
3 y2 + 7
