Answer: (A)=10x5−29x4+33x3−18x2−18x+27

Step-by-step explanation:

How i solved it was by simplifying each answer there was available and (A) was the most compatiable answer!

=(2x+−3)(5x4+−7x3+6x2+−9)

=(2x)(5x4)+(2x)(−7x3)+(2x)(6x2)+(2x)(−9)+(−3)(5x4)+(−3)(−7x3)+(−3)(6x2)+(−3)(−9)

=10x5−14x4+12x3−18x−15x4+21x3−18x2+27

=10x5−29x4+33x3−18x2−18x+27

A rectangle has dimensions 10 cm by 6 cm. determine the measures of the angles at the point of where the diagonals intersect

Sophie [7]

See the attached figure to better understand the problem

we know that

in the triangle ABC
tan(alfa/2)=AC/BC----> 5/3
so
(alfa/2)=arctan (5/3)---------> 59.0362°
alfa=2*59.0362--------> alfa=118.07°
alfa+beta=180°----------> because are supplementary angles
beta=180-118.07-------> beta=61.93°

the answer is
the angles are
alfa=118.07°
beta=61.93°

What is the solution to this equation? 4x+10+3x=40-3x

eduard

Answer:

x = 3

Step-by-step explanation:

Step 1: combine like terms

On the left side, you can combine 4x and 3x to get 7x and the right side is already simplified

Now we have 7x+10=40-3x

Step 2: subtract 10 from both sides

10-10 = 0 and 40-10 = 30

Now we have 7x = 30-3x

Step 3: Add 3x to both sides

7x +3x = 10x and 30-3x+3x = 30

Now we have 10x =30

Step 4: divide by 10 on both sides

10x/10 = x and 30/10= 3

Therefore, we have x =3

Simplify. 1+32⋅2−5 A −48 B 14 C 15 D 27 (Sorry for the first few times it wouldn't let me edit the format)

Inessa05 [86]

Answer:

$\Huge \boxed{\mathrm{60}}$

$\rule[225]{225}{2}$

Step-by-step explanation:

$1+32 * 2 - 5$

Multiplying,

$\Longrightarrow \ \ 1+64-5$

Adding or subtracting,

$\Longrightarrow \ \ 64-4$

$\Longrightarrow \ \ 60$

$\rule[225]{225}{2}$
