Answer:

Step-by-step explanation:

x² + 9x + 18 = x² + 6x + 3x + 18

= x(x + 6) + 3(x + 6)

= (x + 3)(x + 6)

x² + 16x + 63 = x² + 9x + 7x + 63

= x(x + 9) + 7( x+ 9)

= (x + 7)(x + 9)

y² + 13y + 36 = y²+ 9y + 4y + 36

= y(y + 9) + 4(y + 9)

= (y + 4)(y + 9)

(a). Factored form of the expression (y² + 13y + 36) is (y + 4)(y + 9).

Therefore, Lyndsey's answer is wrong.

(b). Factors are (y + 4) and (y + 9).

(c). Factored form of the expression should be (y + 4)(y + 9) instead of Lindsey's answer (y + 6)(y + 6).

A square pyramid has sides of 8 m. Each face is an equilateral triangle.

Annette [7]

Lateral Area means Area of all four triangles

Now area of 1 triangle = $\frac{\sqrt{3}}{4} a^2 = \frac{\sqrt{3}}{4} 8^2$

= $\frac{\sqrt{3}}{4} * 64 = 16\sqrt{3}$ square meters

Now for four triangles we multiply by 4

Lateral area of pyramid = $4* 16\sqrt{3} = 64\sqrt{3}$ m^2

that is Option D

What is (1.2 x 10^-2) x (3 x 10^5)

liraira [26]

Answer:

B. 3.6 x 10^3

Step-by-step explanation:

(1.2 x 10^-2) x (3 x 10^5)

When we multiply terms with powers , we multiply the factors out front and add the exponents

a * 10^b * c* 10^d = ac * 10^(b+d)

(1.2 x 10^-2) x (3 x 10^5) = (1.2* 3) * 10^(-2+5)

= 3.6 * 10 ^3
