It's isosceles triangle, so,

X+X+2.1=7.5
so 2.1+2x=7.5

so ANSWER is D !

Can you help me with this problem

Since there are no actual values, I guess we just have to isolate the b.

2A=bh (multiply both sides by 2)
2A/h=b (divide by h)

hope this helps

Given the function f(x) = 5^x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3. Part A: Find the average r

Wewaii [24]

Table of the graph:
x: 1 2 3
y: 5 25 125

Average Rate of Change = $\frac{y_{2}-y_{1} }{x_{2} - x_{1} }$

Section A = 25-5/2-1 =20/1 =20
Section B = 125 - 25/ 3-2 = 100/1 = 100

So, Section B is 5 times greater than A.
Section B is greater because the slope of two points is greater than points in Section A.

The width of a field is 3 miles less than the length. The square mileage of the plot is 18 miles squared. Find the dimensions.

kherson [118]

LW = A
L(L - 3) = 18
L^2 - 3L - 18 = 0
(L - 6) (L + 3) = 0
L could be 6 or -3 ( -3 cannot be a length of a side of a rectangle since it’s negative.)
So L = 6 and W= 3

Carol Byrd gets a student rate of $30.00 a month. There is a $250 deductible; but no coinsurance payment. She recently received

Alex

Bill = $2,300
Deductible = $250
$2,300 - $250 = 2050
Take 80% of $2,050
80*2050 = $1640
Now $2050 - $1640
Coral = $410.

Hope this helps :)
