X=7 and x+1=8 are two consecutive integers.
Answer:
See attached photo.
Step-by-step explanation:
x = -2y^2 + 4y + 2
It doesn’t show which options?
But the difference would be 2 7/12 or 2.58
Answer:
4√34
Step-by-step explanation:
Let the unknown side be y
y^2 = 20^2 + 12^2
y^2 = 400 + 144
y^2 = 544
Take the square root of both side
y = √544
y = √(16x34)
y = √16 x √34
y = 4√34
