What is the result of isolating x2 in the equation below?(x + 1)2 + ( -8)2 =9A. x2 = -y2 - 2x +16y - 56B. x2 = y2 +2x+16y +56C.
Anit [1.1K]

The expression we have is:

(x+1)^2+(y-8)^2=9

Step 1. Use the binomial square formula:

(a+b)=a^2+2ab+b^2

Applying this formula to the first binomial squared:

x^2+2x+1+(y-8)^2=9

Step 2. Apply the formula for the square of a binomial to the second binomial:

x^2+2x+1+y^2+2(y)(-8)+(-8)^2^{}=9

In this case, we have some operations to solve before we move on to isolating x. So we solve the operations:

x^2+2x+1+y^2-16y+64^{}=9

Step 3. Move the terms that are not x squared to the right side of the expression. Remember that when we move one term from one side of the equation to the other, the term must change its sign. We get the following:

x^2=9-2x-1-y^2+16y-64

Step 4. Combine like terms and arrange terms in order from the greatest exponent to the lowest and leave the independent term at the end:

x^2=-y^2-2x+16y-56

And that is the final result, which is option A.

Answer: Option A.

Figure 1 is a square pyramid. Figure 2 is a right triangular prism.
amm1812

Answer:

the answer is

The surface area of Figure 1 is <u>10.2</u> square centimeters <u>Less</u> than the surface area of Figure 2.

Step-by-step explanation:

Figure 1

area of a square = s2

=9squared

=81 sq cm

area of triangle = 1/2 bh

=1/2 (9cm) (14cm)

=63 sq. cm

find surface area

SA = 81 sq. cm + 4(63 sq. cm)

SA = 81 sq. cm + 252 sq. cm

SA = 333 sq. cm

Figure 2 Calculation

area of rectangle = lw

a = (12cm) (8 cm)

a = 96 sq. cm

area of triangle = 1/2 bh

=1/2 (8 cm) (6.9 cm)

= 27.6 sq. cm

total surface are of figure 2

SA = 3 (96 sq.cm) + 2 (27.6 sq. cm)

SA = 288 sq. cm + 55.2 sq. cm

SA = 343.2 sq. cm

find the difference between figure 1 and figure 2

343.2 sq. cm - 333 sq. cm = 10.2 sq. cm
