Answer:
The answer is B.It is one-half the area of a square of side length 4 units.
Step-by-step explanation:
Given a coordinate grid shown with triangle of measurements with base 4 units and height also 4 units.
We have to find the area of triangle which can be calculated as
⇒
=
we have to choose the statement describes the area of the triangle evaluate above.
Option A: Not matched ∵equals to [area of rectangle of length 4 units width 2 units]=
Option B: matched : given one-half the area of a square of side length 4 units.
⇒
Option C : Not matched : It is twice the area of a rectangle of length 4 units and width 2 units
⇒
Option 4 : Not matched : It is twice the area of a square of side length 4 units.
⇒
So, the correct option is B. It is one-half the area of a square of side length 4 units.
(3) is the base of the new equation
(x + 5) is the answer of the new equation
(2) is the exponent on base (3)
;The new equation after simplifying is...,
; 3^2 = x + 5
; 9 = x + 5
; x = 9 - 5
;Hence...x = 4
Answer:
1/10
Step-by-step explanation:
add 2/5 and 1/2 then subtract from 1 whole to find the remainder
make it so they have the same denominator
2/5 = 4/10
1/2 = 5/10
4/10 + 5/10 = 9/10
1=10/10
10/10-9/10 = 1/10
so 1/10 of the students don't exercise at all
