Answer:
84x¹²
Step-by-step explanation:
it is this because when you multiply -7³×-3⁸= 21¹¹ which means when you times 4x you also have to add a 1 to the exponent which makes it 84x¹²
DH = HF
x + 1 = 3y
y = (x + 1) ⁄ 3
GH = HE
3x – 4 = 5y + 1
y = (3x – 5) ⁄ 5
y = y
(x + 1) ⁄ 3 = (3x – 5) ⁄ 5
5x + 5 = 9x – 15
4x = 20
x = 5
y = (x + 1) ⁄ 3
y = (5 + 1) ⁄ 3
y = 2

domain and range are both all real numbers :)
It would be 10
You substitute “x”for “3” so the equation would be 2(3) + 4. Then you multiply 2 and 3, which is 6. Finally add the 4 to get 10.
The answer:
56 × (x + 15)
