Answer:
7b-c²
Step-by-step explanation:
7times b is 7b reduced by the square of c means minus c²
Answer:
Step-by-step explanation:
(4x4)÷(4+4) = 2
(4x4)÷ (4 +4) - 4= 4
(4+4)+(4÷ 4)- 4= 5
(4+4)- (4÷4) - 4= 3
Answer:
a = -4, b = 3 and c = 6 (OR)
a = -4, b = -3 and c = 6
Step-by-step explanation:
![x^{2} +8x = 38](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B8x%20%3D%2038)
Add 16 to both sides.
![x^{2} +8x+16 = 38 + 16](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B8x%2B16%20%3D%2038%20%2B%2016)
![(x+4)^{2} =54](https://tex.z-dn.net/?f=%28x%2B4%29%5E%7B2%7D%20%3D54)
or ![x + 4 = -\sqrt{54}](https://tex.z-dn.net/?f=x%20%2B%204%20%3D%20-%5Csqrt%7B54%7D)
or ![x+4=-3\sqrt{6}](https://tex.z-dn.net/?f=x%2B4%3D-3%5Csqrt%7B6%7D)
or ![x=-4-3\sqrt{6}](https://tex.z-dn.net/?f=x%3D-4-3%5Csqrt%7B6%7D)
Therefore, a = -4, b = 3 and c = 6 (OR)
a = -4, b = -3 and c = 6
