Answer:

Step-by-step explanation:

Let x represent the smaller integer. Then we have ...

(x +1)² +(x +2)² = 40x +5

2x² +6x +5 = 40x +5

x² -17x = 0 . . . . . subtract (40x+5), divide by 2

x(x -17) = 0 . . . . . factor

The solution of interest is x = 17.

The smaller integer is 17.

43x+2 = 64 + 455 - 766

Rudik [331]

43x+2=64+455−766

Step 1: Simplify both sides of the equation.

43x+2=64+455−766

43x+2=64+455+−766

43x+2=(64+455+−766)(Combine Like Terms)

43x+2=−247

Step 2: Subtract 2 from both sides.

43x+2−2=−247−2

43x=−249

Step 3: Divide both sides by 43.

43x /43 = −249 /43

x = −249 /43

Answer:

x = −249 /43

SVEN [57.7K]

Cost of painting is GHe 109,320

Given:

Floor measure = 15 m by 8 m

Cost of carpeting = GHe 890 per square meter

Total cost of painting and carpeting = GHe 216,120

Find:

Cost of painting

Computation:

Area of floor = 15 × 8

Area of floor = 120 square meter

Cost of carpeting = 120 × 890

Cost of carpeting = GHe 106,800

Cost of painting = Total cost of painting and carpeting - Cost of carpeting

Cost of painting = 216,120 - 106,800

Cost of painting = GHe 109,320
