Solve. 4 - 2x = 10 A) -7 B) -3 C) 0 D) 3

Answers

Answer 1

Answer: 4-2x=10 -4
-2x=6 Divide by -2
X=-3
Therefore the answer is B hope this helps

Answer 2

Answer: It’s D. You subtract four by itself and subtract 4 from ten. Now you have -2x=10. Divide and you get -3

5. What is the area of the figure to the nearest square centimeter? It is composed of a symmetric hexagonand a semicircle 4 cm6 cm3 cm4 cmc 100 cmA 50 cm2D 129 cmB 86 cm

Answers

Area of the given figure is equal to $86\ cm^(2)$ ( nearest square centimeter).

What is area?

" Area is defined as the total space occupied by any two-dimensional object enclosed in it."

Formula used

Area of rectangle = length × width

Area of triangle $= (1)/(2) * base * height$

Area of semi-circle $= (1)/(2) * (\pi r^(2) )$

$r=$ radius of the circle

According to the question,

Given figure is composed of :

two congruent rectangles, four congruent triangles, one semi-circle

Given dimensions,

Length of a rectangle $= 6cm$

Width of a rectangle $= 4cm$

Height of a triangle $= 4cm$

Base of a triangle $= 3cm$

Radius of the semicircle $= (6)/(2)$

$=3cm$

Substitute the value in the formula to get the required area,

Area of a rectangle $= 6 * 4$

$= 24 cm^(2)$

Area of a triangle $= (1)/(2) * 3* 4$

$= 6 cm^(2)$

Area of a semicircle $= (1)/(2) * \pi * 3^(2)$

$=4.5 * 3.14\n\n= 14.13 cm^(2)$

Substitute the value to get the required area,

Area of the given composed figure $= 2* 24 + 4* 6 + 14.13$

$= 48 + 24 + 14.13\n\n= 86.13 \ cm^(2)$

≈ $86 cm^(2)$ (nearest square centimeter)

Hence, Option(B) is the correct answer.
