Answer:

x = 13 smaller integer

x + 2 = 15 the other integer

Step-by-step explanation:

x = the smaller integer

x + 2 = the next integer

7(x) = 61 + 2(x + 2)

7x = 61 + 2x +4

5x = 61 + 4

5x = 65

x = 13 smaller integer

x + 2 = 15 the other integer

Can someone plz solve for A&B? Plz and if you do thank you so much :)

Answer:

Part a-

area= 35

perimeter= 31

part b-

area= 25

perimeter= 18

Step-by-step explanation:

to find the area of a triangle you multiply 1/2Bh

so for part A:

A= $\frac{1}{2}$ (10)(7) (honestly, you can just input the whole equation into the calculator)

A=(5)(7)

A= 35

and for part B:

A= $\frac{1}{2}$ (8.34)(6)

A= (4.17)(6)

A=25.02 (or just 25)

THEN, to find the perimeter you add up all of the sides

so for part A:

P= 14 + 10 + 7 = 31

and for part B:

P= 4 $\frac{1}{3}$ + 8 $\frac{1}{3}$ + 5 $\frac{1}{3}$ = 17 $\frac{3}{3}$ or 18

I hope this helps :)

Find two consecutive even interferes such that 4 times the smaller is 18 more than 3 times the larger.

Artemon [7]

The numbers are 24 and 26

Step-by-step explanation:

Step 1: Let the integers be x and (x+2). Here the smaller integer is x and the larger integer is x + 2.

Given that 4x = 18 + 3(x + 2)

⇒ 4x = 18 + 3x + 6

⇒ 4x = 24 + 3x

⇒ x = 24 and x + 2 = 26
