valkas [14]3 years ago
4 0

Answer:

            P = 4x  +  10

Step-by-step explanation:

perimeter of a rectangle = 2( width + length )

   P = 2 ( x - 2  +  x + 7 )

   P = 2 ( x + x  +  7 - 2 )

        P = 2 ( 2x +  5 )

            P = 4x  +  10

3 - 4 x 2 The first step to evaluate the expression is ...
sveticcg [70]

To find these out you have to use the strategy of P (parenthesis) E (exponents) M (multiplication) D (division) A (addition) S (subtraction)

3 - 4 x 2 The first thing you need to do is do the multiplication part first, since subtraction is the last thing you need to do. You multiply 4 and 2 and get the answer of 8, then subtract 3 which is 5

5 x 3 - 4 The first thing you need to do is multiplication 5 x 3 which equals 15 and then do 15 - 4 = 11

15 ÷ (3 x 5) x 2 The first thing you do is you do the P (parenthesis) which is (3x5) which equals 15. Then you multiply 15 with 2 which is 30 and then divide 30 with 15 which is 2

5 + 3 x 2 ÷ 6 First you need to do the Multiplication which is 3 x 2 which equals 6, and then you do the division, which is 6 ÷ 6 which is 1. Then add 5 to the 1 which is 6.

What is the equation of the following line? Be sure to scroll down first to see all answer options.
Colt1911 [192]

Answer:

E

Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 0) and (x₂. y₂ ) = (8, 2) ← 2 points on the line

m = \frac{2-0}{8-0} = \frac{2}{8} = \frac{1}{4}

y = \frac{1}{4} x → E

50. If angles are complementary, what’s value of x?
maks197457 [2]

Answer:

x = 14

Step-by-step explanation:

For complementary angles, the sum of two angles is equal to 90 degrees.

We have,

m\angle ABC = 4x-10\\\\m\angle DBC = x+30

ATQ,

4x-10+x+30=90

Taking like terms together,

4x+x =90-30+10

5x = 70

x = 14

So, the value of x is 14.
