What is it about. I think I can help you just got to explain what you need to do
A) Height -7 = base
B) .5 * height * base = 60
Substituting A into B
B) .5 * height * (height -7) = 60
B) .5*height^2 -3.5*height = 60
B) .5*height^2 -3.5*height -60 = 0
Using the quadratic formula:
Height = 15
Subtracting 7 gives us the base length
Base = 8
**************************************************************
Double-Check
.5 * 15 * 8 = 60

The right answer to your question is the third option
Step-by-step explanation:
5 √12xm³
First find the prime factors of 12
12 2
6 2
3 3
1 Then 12 = 2² 3
and m³ = m m²
So 5 √ 2² 3 x m m²
and 5 (2)(m) √ 3xm
10 m √ 3xm
Answer:
The price of today's bread is $7.
40% of $7 is $2.80.

The price of yesterday's bread is $4.20
Tobin has enough money to purchase a loaf of yesterday's bread.
Hope this helps!
Answer:
Look at explanation.
Step-by-step explanation:
<em><u>Dilation of scale factor of 5, because it would become more wide and open by a factor of 5. Reflection over y-axis, because it makes the shape double the size. Dilation of scale factor of 1/2, because it makes the shape half it's size.</u></em> The rotating 90 degrees would only change the shapes position, not the size. The translation would only move the shape to a different area, and not change the size.
