Answer:
Width=6.5 cm
Length=12 cm
Step-by-step explanation:
Step 1: Express the lengths and widths
Width=w
Length=l, but 1 cm less than twice the width=(2×w)-1=2 w-1
Step 2: Solve for the length and width
A=L×W
where;
A=area of the photograph
L=length of the photograph
W=width of the photograph
In our case;
A=91 cm²
L=2 w-1
W=w
91=(2 w-1)w
2 w²-w=91
2 w²-w-91=0, is a quadratic equation
solve for w
w={-1±√(-1²-4×2×-91)}/(2×2)
w=(-1±27)/4
w=(27-1)/4=6.5, or (-1-27)/4=-8
Take w=6.5 cm
L=(2×6.5)-1=13-1=12 cm
Width=6.5 cm
Length=12 cm
Answer:

Step-by-step explanation:
So for Tom to get his free meal he needs to spend 50 dollars.
This means the following⬇️
This equation is the 50 dollars he has to spend minus the 30.25 he has already spent which results in⬇️
This results in Tom needing to still spend 19.75 more dollars to get his free meal!!
Hope this helped!!
Answer:
x = 2 and y = 3
Step-by-step explanation:
For us to have a parallelogram, the opposite sides must be equal in length
Thus, we have it that;
2y + 2 = y + 5
2y - y = 5-2
y = 3
To get the value of x
y + 4 = 2x + 3
Recall y = 3: substitute this value
3 + 4 = 2x + 3
3+ 4 - 3 = 2x
2x = 4
x = 4/2
x = 2
They have different angle's degrees acute are degrees lesser than 90°, and right angle are 90° only, and obtuse angles are angle degrees more than 90° degrees
