Answer:
see explanation
Step-by-step explanation:
The side of the square = x + 2, thus area is equal to
(x + 2)² ← expand using FOIL
= x² + 4x + 4
Given area = 7 then
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required
Answer:
The highest price is of peppers $1.62
Step-by-step explanation:
Cost of turnips per pound = $1.51
Cost of peppers per pound = $1.62
Cost of the carrots per pound = $1.26
Cost of celery per pound = $1.48
As all the costs are given in the same unit prices, we can simply compare the prices to find out highest value.
The highest price is of peppers $1.62.
Question should be sin 20 cos 10 + cos 20 sin 10
remember sin (a+b) = sin a cos b + cos a sin b ?
sin 20 cos 10 + cos 20 sin 10
= sin (20+10)
= sin 30
= 1/2
The catapult arm length for their tennis balls to cover the same distance is 32.3 feet.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Given the equations:
Aiden: y = 2.3x + 160.7
Natalie: y = 3.6x + 202.6
For their tennis balls to cover the same distance:
2.3x + 160.7 = 3.6x + 202.6
1.3x = -41.9
x = -32.3
The catapult arm length for their tennis balls to cover the same distance is 32.3 feet.
