Answer:
Step-by-step explanation:
Perimeter = 2*(length +width)
P = 2*( x+8 + y-1)
P = 2*(x + y + 7)
P =2x + 2y + 17
Answer:
number 1 is 5x 1/2 the others I'd not know
121^4-49
(11^2+7)(11^2-7) 1. 121. 49
11. × 11. 7 × 7
Answer:
first of all the formula
y = mx+c
where m is slope and c is y-intercept.
now substitute the values-
y = 2x - 5
(for the slope here is 2 and the part where the line intercepts y axis is -5
therefore
y = 2x-5
