1-44. For each expression below, build a rectangle using all of the tiles, if possible. Sketch
each rectangle and label its dimensions. Write an equation that shows that the area
written as a sum (such as X^2+6x + 8) is equivalent to the area written as a product
(such as (x + 2)(x + 4)). If it is not possible to build a rectangle, explain why not.
a x^2+ 8x + 12
b. 4x^2+ 4x
C.2x² + 7x+1
d. x^2+ 2xy + y^2
с.
2r + 7x + 1

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

what are you trying find out?

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
