The area of a circle with a radius of 26 would be <span>2123.72 ft.</span>
3x + 2y = 12
5x - 2y = 4
When adding the 2 equations, the y's will cancel.
8x = 16 divide both sides by 8.
X= 2
The given expression is a result of squaring binomials
<h3>Factoring quadratics </h3>
From the question, we are to determine whether the given expression is a result of multiplying conjugates together, squaring binomials, or neither
The given expression is
9z² +54z +81
To do this,
First, we will factor the expression
Factoring the expression
9z² + 54z + 81
First, factor out 9
9(z² +6z +9)
9(z² + 3z + 3z + 9)
9[z(z + 3) + 3(z + 3)]
9[(z +3)(z +3)]
9[(z +3)²]
This can further be expressed as
3²[(z +3)²]
[3(z +3)]²
(3z +9)²
Hence, the expression is a result of squaring binomials

Mr. Giarmo arrived at work at 7:40 a.m.
Answer:
The error is the slope is -4 and the correct is, the slope is
Step-by-step explanation:
You must put the equation in the form of y = m x + b, where
Let us put the equation n the form above
∵ x = -4y
→ Switch the two sides
∴ -4y = x
→ Make the coefficient of y equal 1 by divide both sides by -4
∵ =
∴ y =
→ Write as x
∴ y = x
→ Compare it by the form above
∴ m = and b = 0
∴ The slope of the is , and the y-intercept is 0
∴ The error is the slope is -4 and the correct is the slope is
