Answer:
Length of diagonal of picture = 15.30 inches
Step-by-step explanation:
Given that:
Side lengths of picture frame = 12 inches by 9.5 inches
As the picture is rectangular, the diagonal will form hypotenuse of right angled triangle.
Using Pythagorean theorem;
a²+b²=c²
Putting the values in the theorem

Taking square root on both sides

Hence,
Length of diagonal of picture = 15.30 inches
Part A
Distribute the one-half.
1.24g + 0.87m + 0.98z
Part B
(29.68 - x) + 14.45
Or simplified to 44.13 - x
Part C
a = number of times at the store
b = gloves' price
c = hat's price
Answer:let the invstmt be X and Y
X+Y=34000
0.02X+0.03Y=890
0.02(34000-Y)+0.03Y=890
680-0.02Y+0.03Y=890
0.01Y=210
Y=21000
X=13000
Step-by-step explanation:
When you group pairs of terms and factor each group, you get
x³(2x + 5) – 4(2x + 5)
