Hey there
<span>240 times 365 can be written as 240 x 356.
</span><span>240 x 356 = </span>87600
So what they are telling you is that 5 is three higher than the variable n.
So n = 5-3
so n is 2.
Answer:
2x + y = 5
y = 4x – 1
Substitute (2, 1) into system, then:
2x + y = 5 => 2 x 2 + 1 = 5 => 5 = 5 (satisfied)
y = 4x– 1 => 4 x 2 - 1 = 1 => -7 = 1 (not satisfied)
=> Option 3 is correct.
Hope this helps!

The length is 7 with a width of 5, so the area is 35
