Answer: 10
Step-by-step explanation:
Hi,
(a+b)² = a²+2ab+b²
For a = 2 and b = 5
(2+5)² = 2²+2(2)(5)+5²
(2+5)² = 4+20+25
(2+5)² = 49

Answer:
y = 8x + 7
Explanation:
The equation of the line in slope-intercept form has the following general formula:
y = mx + c
where:
m is the slope of the line = 8
c is the y-intercept = 7
Substitute with the givens in the above formula to get the slope of the line as follows:
y = mx + c
y = 8x + 7
Hope this helps :)
Answer:
The numbers are either {-3, -2, -1} or {7, 8, 9}.
Step-by-step explanation:
Let the smallest integer be represented by x. The middle number is x+1, and the largest number is x+2.
The product of the smaller and larger number is (x)(x+2).
15 more than 6 times the middle number is 6(x+1)+15.
(x)(x+2)=6(x+1)+15
x^2+2x=6x+6+15
x^2+2x=6x+21
x^2-4x-21=0
(x-7)(x+3)=0
x=-3 or x=7
The numbers are either {-3, -2, -1} or {7, 8, 9}.
