Answer:
none of these
Step-by-step explanation:
2x² + 7x + 4
Factor
We cannot factor this since 2*4 +1 = 9 and we want 7
and 2*2 +2 = 6 and we want 7
and 2*1 +4 = 6 and we want 7
Answer:
(5, -9)
Step-by-step explanation:
Answer:
81 and 9
Step-by-step explanation:
Okay, so if 2 angles are complementary, it means that when they are added together, they equal 90 degrees. So using this, we can make an equation. Let's call one angle x and the other that is 72 less than angle x can be described as x - 72. Now let's make that into an equation.
90 = x + x -72
So in order to solve this, we need to get x by itself. So we need to add 72 on both sides, and the equation should now look like this:
162 = x + x
Now we have to add the x's together.
162 = 2x
Now in order to isolate x, you divide by 2 on both sides.
X = 81
So we now know the larger angle is 81, and the smaller angle which is 72 less, would be 9.
22×2= 44 (for the pants)
92-44= 48 (total for shirts)
48÷4 (total number of shirts)= 12 per shirt
Answer:
£69.33
Step-by-step explanation:
4/3=1.33333333333 so that 52*1.33333333333 would convert 52 euros into 52 pounds
