It’s B plug in -1 to x and -7 into y
Answer:
Step-by-step explanation:
length : 2x
width : 3x+2
Perimeter = 2(l+w)
substitute in knowns
74 = 2(2x+3x+2)
combine like terms
74 = 2(5x+2)
distribute
74 = 10x+4
subtract 4 from each side
70 = 10x
divide by 10
x=7
Answer x=10
Answer:
t =5
Step-by-step explanation:
-7(2-t)=21
-14+7t=21
7t=35
t=5
Answer:

Step-by-step explanation:
The area of triangle is 13905.5 cm square when height is 137 cm and bae is 203 cm.
Given that,
There is a triangle with height 137 cm and base 203 cm.
We have to find the area of triangle.
We know,
The entire area filled by a triangle's three sides in a two-dimensional plane is referred to as the triangle's area. A straightforward formula can be used to get the area of a triangle by multiplying the sum of the base and height by two.
Area of triangle =1/2×b×h
Area of triangle =1/2×137×203
Area of triangle =1/2×27811
Area of triangle =13905.5
Therefore, The area of triangle is 13905.5 cm square when height is 137 cm and bae is 203 cm.
