Answer:

option A

Step-by-step explanation:

find the following expressions results in 0 when evaluated at x = 4

we plug in 4 for x  and see which expression gives us answer 0

A)(x - 10)(x - 4)

(4 - 10)(4 - 4)=0

B)(x + 4)(x - 10)

(4 + 4)(4 - 10)=-48

C)4x(x - 6)

4(4)(4 - 6)=-32

D)(x + 6)(x - 2)

(4 + 6)(4 - 2)=20

The values of angles are 140 and 20

• In plane geometry, a figure which is formed by joining of two lines that share a common point is called as the angle. The two lines or rays are called as the sides of the angle and the common point is called the vertex.

• In geometry there are types of angles such as complementary angles, supplementary angles, acute angle, obtuse angles. Complementary angles are the angles whose sum is equal to 90. Supplementary angles are the angles whose sum is equal to 180.

According to the question

We are given that one angle is -7x and the other angle is -2x

Using formula of supplementary angles

-7x + (-2x) = 180

-7x -2x = 180

-9x = 180

-x = 20

x = -20

The value of x is -20

The value of angle – 7x = -7(-20) = 140

The value of angle -2x = -2(-20) = 40

The three numbers are in the ratio 2 : 3 : 4 and the sum of their cubes 12375
larisa86 [58]
Let us take each number as x = 2x , 3x,  4x 
(2x)³+(3x)³+(4x)³=12375
8x³+27x³+64x³=12375
99x³=12375
x³=12375/99 
  =125
x =∛125
x=5
2x=2×5=10
3x=3×5=15
4x=4×5=20

therefore, the three numbers are 10,15 and 20 .....

Hope it helps !!

Need help for4,5,6 dealing with isosceles triangles
Debora [2.8K]
HP = JP (since the opposite sides of an isosceles triangle are equal)
3x - 6 = x + 2
2x = 8
x = 4

Thus, HP = 3(4) - 6 = 12 - 6 = 6
JP = 4 + 2 = 6
JH = 2(4) = 8.
