Answer:

Step-by-step explanation:

z² - y

z + 2y

when y = 3, z = 5

substitute values:

= 5² - 3

5 + 2*3

= 22

5 + 2*3

= 22 / 11

= 2

Someone help me with this find points a b c

NISA [10]

Answer:

<a=32

<b=40

<c=40

Step-by-step explanation:

to find angle a you have to subtract the 50 minus 180 to find the angle close to the 50 because angles in a straight line add up to 180. the answer will be

180-50=130

after finding the angle in that triangle you must add it to the other angle present which is 18° then subtract by 180 because angles in a straight line add up to 180

130+18+a=180

a=180-148

a=32 and that's how you find a

to find b you must know that the angle at the center is twice the angle at the circumference meaning the large angle C is 90°,now if it's 90° inorder to find the big angle B you must add the 18+90 then subtract 180

18+90+B=180

B=180-108

=72

since the combination of angle a and b will give you 72 you can find angle c by subtracting a from 72

c=72-32

=40

then if you look at angle c and angle b you can tell that they are alternating meaning angle b is also 40

I hope this helps

How many triangles and quadrilaterals altogether can be formed using the vertices of a 7-sided regular polygon?A. 35B. 40C. 50D.

kondaur [170]

Answer:

E) 70

Step-by-step explanation:

Using combination factorial

a triangle has three vertices and a quadrilateral has 4 vertices

The number of triangles and quadrilaterals = ⁷C₃ + ⁷C₄ = $\frac{7!}{4!3!} + \frac{7!}{4!3!}$ = 70

Which phrases can be used to represent the inequality mr024-1.jpg? Check all that apply. The product of 6.5 and the sum of a num

Bogdan [553]

INequality represents which of the numbers or expressions that are given produces a greater than, less than, greater than or equal to, less than or equal to or equal to the the number being compared. You need to know that greater means this sign ‘>’, lesser means ‘<’ sign, greater than or equal to means '≥', less than or equal to means '≤' and equal to '='. The phrases that can be used to represent the inequality are:
The product of 6.5 and a number, when increased by 1.5, is below 21.
6.5x + 1.5 < 21
The sum of 1.5 and the product of 6.5 and a number is at least 21.
6.5x + 1.5 ≥ 21
The product of 6.5 and a number, when increased by 1.5, is at most 21.6.5x + 1.5 ≤ 21
